Why wouldn't dinosaurs allow homo sapien to exist and advance if they didn't go extinct?

I keep hearing "human race would never exist or civilize if dinosaurs didn't become extinct".

Just curious. Couldn't both have Co existed? A lot of animals already co exist and dinosaurs are no different.

    Humans are primates . Primitive primates did not evolve until after the dinosaurs have been extinct for some 10 million years. If dinosaurs did not become extinct, primitive primates may not have evolved. No primitive primates then no monkeys. Since apes evolved from a monkey and humans evolved from an ape. That means we could not have evolved if primitive primates did not evolve.

    That may be because humans are large mammals. We can weigh 150 pounds or more. Most living mammals in contrast are rodents and bats, and most of them weigh a few ounces or so. We may not be considered large compared to elephants and rhinos or whales, but we are large compared to most other mammals.

    During the age of dinosaurs, which lasted about 150 million years, no large mammal the size of humans or larger existed. Most of the mammals were living underground, inside burrows, and they came out at night to feed on insects. There were some medium sized mammals, such as the platypus in Australia. There were medium sized marsupials living in North America, they were about the size of a house cat.

    Things were quite different after dinosaurs were wiped out 65 million years ago. mammals evolved to be much larger in their absence. A mere 30 million years after dinosaurs became extinct, Indricotherium, one of the largest land mammal that has ever lived, had evolved. The climate may have been a factor too, because Indricotherium evolved at the same time that the climate cooled, and Antarctica froze for the first time in its history. Since mammals generate their own body heat, and since large mammals have proportionally small surface area to volume ratios, large mammals can conserve heat better during a cold climate but they have trouble avoiding heat stroke in a hot climate. The climate during the age of dinosaurs was hot, and that may have kept big mammals from evolving. Indeed Indricotherium became extinct when the earth briefly warmed up again, about 23 million years ago, when Antarctica thawed briefly before re-freezing shortly afterwards. Nevertheless, dog-sized mammals evolved within 15-20 million years after the dinosaurs were gone, when the earth's climate was still as hot as the age of dinosaurs, so climate appears not to be the reason mammals failed to attain large size before the dinosaurs were wiped out.

    In ecology, there is a term known as competitive exclusion, and it predicts that two species that live in the same place at the same time cannot coexist if they have similar needs. Every species has its own niche, and no two species that occupy the same niche can coexist in the same place at the same time. One of them will be eliminated by competition, driven to extinction, or both of them will evolve to have different niches so as to avoid competition. During the age of dinosaurs, all available niches for large land animals were occupied by dinosaurs and other reptiles. A new species of mammal that tries to evolve to occupy the same niche as an existing species of dinosaur would face stiff competition and will most likely be eliminated.

    OTOH, after a mass extinction, there are many available niches that are suddenly open and unoccupied. In the absence of competition, new species that can evolve to fill these niches can easily survive. That is why we see an adaptive radiation, or a proliferation of new species after a mass extinction. After the dinosaurs were wiped out, the surviving mammals underwent adaptive radiation and they evolved into the variety of large mammals we see today. The ancestors of the living orders of mammals had evolved just 5-10 million years after the dinosaurs were gone. Giraffes, cows, hippos, horses, elephants, kangaroos, rhinos, lions, tigers and wolves all evolved after dinosaurs were wiped out. Their ancestors were tiny shrew-like mammals the survived the meteor strike that wiped out the dinosaurs.

    They would have been too big to survive. Mammals evolved from cynodonts, a group of superficially dog-like mammal-like reptiles in the wake of the Permian–Triassic mass extinction. The emerging archosaurian groups that flourished after the extinction, including crocodiles and dinosaurs and their ancestors, drove the remaining larger cynodonts into extinction, leaving only the smaller forms. The surviving cynodonts could only succeed in niches with minimal competition from the diurnal dinosaurs, evolving into the typical small-bodied insectivorous dwellers of the nocturnal undergrowth.

    We were programmed to believe a lie.

    It was easy to believe, because we have prehistoric evidence of it staring us in the face: I mean, we have the dinosaurs, right?

    This may change your mind (or not... depending on what you WANT to believe):

    The word 'dinosaur' came from two Greek words that mean 'terrible lizard': a word made up in the 1800s to describe reptile fossils.

    The word 'fossil' is from the French for 'dug up'.

    Under the forces of extreme pressure, everything that was engulfed in mud during the world-wide flood turned into stone.

    For about a year and a half minerals permiated plant and animal tissue. The mud also became stone as it compressed under the weight of billions of tons of water.

    - Stone cannot be dated.

    - Once around the sun is a year: you cannot hold up a rock and decide how many times it has been around the sun.

    *When a fish dies, it rots or gets eaten.*

    It does NOT turn into a fossil.

    But there are fish fossils everywhere on the planet (even on the tops of mountains).

    Every fossil in the world is the result of the world wide flood. Period.

    *Before the flood everything lived ten times longer*

    that's why

    tusks

    antlers

    fangs

    trees

    bugs

    and reptiles grew huge.

    I used to work with reptiles: among many things I learned about them was that they NEVER stop growing as long as they live.

    Pre-flood the air had 50% more oxygen in it.

    Hyper-oxygenated air; the world was like a hyperbaric chamber, everything lived longer because of the air quality.

    We know this because we have air samples from before the flood; extracted from bubbles trapped in fossilized sap (amber).

    Adam lived until he was 930. Noah was 600 when he built the Ark (Google Noah's Ark Turkey - a tourist attraction since the 1970's A.D.).

    Believing in lies about evolution makes you guilty of making God out to be a liar. This is slander against the Most High: spiritual treason.

    You've heard of bacteria 'evolving'?

    No such thing: simply, the hardier bacteria were never killed off by the antibiotic in the first place. The weaker bacteria were. All that's left is 'resistant' bacteria. They were never subject to antibiotics to begin with. They never 'evolved'.

    Want to see evolution?

    If God wants to raise children for Abraham from the stones He can do it.

    He doesn't need any of us.

    He can change what is in the blink of an eye.... He doesn't need millenia.

    No. Mammals were no bigger than mice at the time, because dinosaurs would eat them. Literally, apes wouldn't have evolved at all.
