But conditions on Earth were “perfect” for life to exist because this is where all the life we’ve ever seen evolved.
If conditions on Earth was different, life would have evolved differently and people would still say conditions were “perfect” it’s survivorship bias.
So earliest life likely sprung up with some pretty fundamental differences, and whatever evolved best hung around.
We can see modern versions of this when extremophiles overlap due to changing conditions. Life forms that have been isolated thousands (sometimes millions) of years. Or even just the life that exists in deserts for the brief period there’s puddles after a rain.
Earliest life was probably just a bunch of isolated pockets, who were eventually able to evolve and spread out from the extreme environments they came from. Sometimes they take over and spread, others they die out and only the ones that stayed in their extreme environment survives.
It almost certainly did…
