Don’t you know chance plus billions of years solves this problem.
As if they personify “chance” and “loads of time”. As if they are deities!
And they do. They use terms such as “nature tells us” “mother nature” and today some are bold to show their true beliefs and use Gaia.
Do you not understand that there are fish today which can breath air and spend part of their lives away from water?
On the other side, there are reptiles, birds and mammals which live in water and according to fossils have become steadily more aquatic.
So what exactly is your problem with that?
