I have been trying to explain evolution to my stepmother who believes god created everything. She does halfway understand that evolution is a fact and it took billions/millions of years. But for some reason she does not understand that there may have been dozens of different types of bacteria living in the primordial sludge not just one. I have tried to explain that perhaps not everything evolved from the same one celled lifeform. I have tried to explain that when the conditions for life were right, it is possible that many different types of bacteria grew. Or maybe a meteor from another plant had some bacteria on it that introduced other forms of life to ths one. My point is just because life is diverse does not mean god made it that way. Who knows maybe some ancient astronaut came here and relieved itself and we all evolved from the bacteria in that poop. The presence of bacteria is not proof of the existence of god.
She also claims that God created the Big Bang. First off, points to her for even knowing or trying to understand the big bang. She says before the big bang, there was god. So I asked her who created god? God was just first. Okay, but if everything has to be created by something, doesn't something have to have created god?
She's the diversity of life and the evolution of intelligent beings is proof of god. I said there is more than one intelligent lifeform on this planet. There are several animals out there, I would say are fairly smart. In fact, many animals are pretty intelligent for what they are, where they live and how they live. Maybe it doesn't require a 10 pound brain to be a worm. However, dumb worms get eaten or die too young to reproduce. It's a everything eats worm world out there for worms, so maybe for the life that they lead, they are pretty smart. Maybe intelligence and life are the rule not the exception. Maybe the universe is teaming with life, we just haven't gotten out there to see it.
How do I explain to her that life evolves regardless if there is a god around or not? I'm not trying to steal away her sky friend, just trying to explain he doesn't do everything and he's not in charge of everything.
