I grew up in a non religious household, and my dad especially would often dunk on religion whenever it came up. When I was a dumb 8 year old, I made up an experiment to see if magic or god really existed. So I chose something that I thought was random and had a small chance of happening and try to make it happen by praying/manifesting/whatever. My parents have a low opinion on reptile pets and would always say that they didn't fucking do anything so I decided that getting a gecko was unlikely and strange enough to be proof, but also easily attainable, so it was easier for my "timeline" to shift in that direction. I never mentioned it to anyone, but I would often pray or think about it and sort of imagine my thoughts integrating with reality to make it real. For several years I would think about it often until I stopped caring. Fast forward a decade and my mom suddenly decides that a good present for my brother would be a gecko despite him never mentioning it. I had completely forgotten and said nothing about it and didn't realize until I saw it that My wish/prayer/manifestation had come true.
It is a very boring animal. It stays in its little hollow rock and never comes out, and hides when it hears you. But the gecko happened. I am still non religious, and will be forever because of personal ideas, but Its kind of cool and I think about it sometimes. This was supposed to be the ultimate proof that god or magic existed, but I don't care anymore.
