It's funny how you keep running back to this silly stuff.
Nobody starts with a blank page and just evidence.
Everyone has the SAME evidence, but look at it differently depending on their assumptions about the nature of things.
There is NO unequivocal and unambiguous evidence that all life on earth has descended from a universal single common ancestor.
It was NOT pristine beautiful evidence ALONE that led to that idea.
Um, no RD, that's not how science works so no wonder you keep making the same mistakes. Assumptions, personal beliefs, preferences about how things should be are entirely irrelevant. If a theory doesn't stand up to continual scrutiny and testing then it's altered accordingly or even discarded. Science is not interested in personal beliefs, whatever they might happen to be. The theory of evolution did not come about because scientists the world over wanted to wind up young earth creationists. It came about because of the evidence. The global consensus in the scientific community regarding it is again, because of the evidence that supports it. Plenty of scientists are also Christians.
It may be crucial for you to have an earth that's no older than ten thousand years old but science doesn't care.
