Why did life choose calcium?

Are there any theories about why life ended up choosing calcium as the non-organic mineral from which its skeletons are built from? As far as skeletons go, wouldn't choosing metals like iron, aluminum, etc. have been a stronger choice?

    Calcium ions are more water-soluble and abundant.

    My theory is calcium was available and it works. Aluminum is common but not easy to chemically isolate. And basically iron oxides.
