I also like your theories as to where we all came from/what’s the meaning of life? etc. I tend to think we are just biological critters and driven largely by biological motives for food, sex, air, water etc.
Being more intelligent than other animals we can perceive a lot more and can think about deeper concepts (such as where did it all come from?). Our need to explain is cool, because it helps us explore our world and learn about better ways to live. This has resulted in us going from primitive life to increasingly complex lives, and it has also made us believe we hav
e all the answers, and it allows many of us to make up answers for that we don’t understand, and then after a long period of accepting these made up explanations, they become truth in many circles. One example is the belief of the Earth being the centre of the universe and our solar system, and the Catholic church punished Galileo when he contradicted the church’s concocted explanation.

There are many explanations based on science, but there’s always another question of “but where did that come from?”, or “how can that occur?”. Looking at the Galileo example I think we can safely assume that although we don’t know many things, we can keep looking for sensible answers, accept that there are still some unknowns in the universe, and not look to people who want to make up simple and childlike explanations to explain what they don’t understand (it must have been god).
