Is it weird that life formed on earth at the exact same time Venus became uninhabitable?

Update:

Did advanced Venusians facing extinction travel to Earth and caused life to grow via panspermia?

    Venus was never habitable, due to its toxic atmosphere and its proximity to the sun.

    "became uninhabitable" - and how do you know it was ever habitable, or when it became uninhabitable.

    That is simply not true.

    Life began on Earth within around half a billion years of its formation, plus or minus a few hundred million.

    The "Inhabitable Venus" theory puts that as habitable for something like two billion years, so conditions did not significantly degrade until long after life began here.

    (If Venus was ever habitable).

    And: It's taken another four billion or so years for life on Earth to become advanced enough to think about space travel, so rather unlikely any civilisation developed on Venus before conditions changed.

    No.  How do you know that Venus was ever habitable ?  How do you know when it became uninhabitable ?

    Venus became as it is a long time ago. Venusians, if they ever existed, didn't have time to become advanced. However, Venus and Earth may once have been similar and there may have been microbial life on Venus, billions of years ago.
