Lepton
I grew with Catholic religion being brainwashed into me but since I am a person that questions everything I found religion to be hypocrites. My core belief was centered around a God and being a good person. In my early thirties I decided to educate myself on how religion came about and its history and what dawned on me is the belief that man created God and not the other way around. I remember one day thinking, Wow I don't believe in God anymore, am I okay? At that moment my core belief had changed and it took me a little while to realize it.
Many people I know do not want to learn about what science says on the subject of our history due to their core belief in religion. Perhaps they feel disloyal or the information is too overwelming to comprehend it. I am a sponge in that I can't wait for something new to be discovered especially in genetics and microbiology. I have studied just about every subject in science and the history of life for about 10 years now and I love it.
