1. Abiogenesis. For such a simple event, it's amazing how we still haven't come close to creating life. We have our ideas of how it all happened, but for some reason nothing materializes. Not even close.
2. I saw that Atheists were starting to act like religious fanatics. Ascerting that their beliefs were fact, even though they aren't. Some even started handing out pamphlets and started churches of Atheism. One reason I was an Atheist is because I was happy not being associated with fanatics.
3. The more I studied science, the more I realized we didn't know. For instance, our own brains. Most brain surgery is truly barbaric. Honestly, we have hardly a clue about how our own brain works. If we can't scientifically understand ourselves, how can we understand something as complicated as a God?
4. Every month is seems like I come across more proof behind the Bible. In the past 20 years, despite past doubts and criticism, we have proven that Pontius Pilate, King David, King Nebuchadnezzer and his amazing "floating" gardens all existed. We have found architecture that proved that Samson's story (the two pillars story) was plausible. Before that, people said that no culture ever made buildings dependent on two pillars. We have also proven that the Exodus did happen. The only thing is that it appears to have been over a longer period of time, not all the Hebrews migrated at the same time.
5. Going scuba diving in Costa Rica makes it so hard to believe that the fish in the sea were just something that happened. Especially if you ever see an octopus camouflaged. It's beautiful and amazing.
6. I looked at the past scientific theories and saw how they were practically considered fact in those times, but now are plain ol' silly. For example, Atheists used to base evolution off of a simple experiment. Put dung on the ground, eventually dung beetles come out of it. There you go, a solid theory at that time. Now, laughable.
7. After meeting a few sociopaths, I now understand Satan.
