I remember years ago back when I was an atheist, I read someone on Reddit or somewhere saying the fact humans get sleepy after sex is proof of evolution. They said it proves evolution because humans go to sleep when their job is done, which is to reproduce. Now, at the time I was an atheist, and of course I still 100% believe in evolution today, but that random person's comment stuck with me for years.
See, the idea that people go to sleep after sex because their job is done makes for a good story. I don't know if it's true, but it sounds good. Thing is, the good story isn't exclusive to evolution. Bible says Elohim told humans to go forth and be fruitful. So if Elohim had created humans, he would have made humans sleepy after sex too. Obviously.
This random guy on the internet whose comment I read years ago, he saw a piece of evidence that made a good story for his views, and he didn't actually check whether it was evidence against the opponent's views. I think he just assumed that the two models had to be opposed in every single way and any evidence for his views was evidence against the opposite. He was basically the same as the banana guy.
You know the banana guy? "Bananas are proof of Deus because they're perfect for eating ". Guy didn't do his research and didn't realise humans made bananas the way they are. He found a good story and didn't check if it was also a good story for the other guys. Same as the sleepy sex guy.
You gotta be able to see the other side's viewpoint enough to check whether your evidence can be explained by their views, or if you're just embarassing yourself. That's the bare minimum of understanding other people's views. Without it, you end up like the banana guy.
