Questions like "Why are we here? Who cares? What is our purpose?" are ABSOLUTELY within the province of Religion and the (secular) Humanities, not science.<quoted text>
Many scientific facts are being questioned on various venues and subjects. Science has a hard time explaining a lot of things. Faith is being questioned on many levels and throughout the world. What is true? What is made up? How do we know that we were not misled from the beginning? The snake. The apple. The garde. Both are interesting subjects. Not one can claim to be totally right. One requires theories that may or may not be correct, the other requires blind faith that may or may not be justified. People seem to require things like this. Why are we here? Who cares? What is our purpose? To poop? To breath? To live? To reproduce? To die? Who created us? God? Nature? Gods? Our parents? Their parents? Adam and Eve? Aliens? Where did we come from? The ground? The air? The water? The fire? The ether? Where will we go? The ground? The water? The air? The ether? It's all about what you believe, whether it is true or not is irrelevant. The truth is none of us will ever know more than what we read in fairytales of floods, gardens, sacrifice and supreme beings or scientific theories.
Questions regarding facts are within the realm of science.
You need to understand the differences in focuses and which arena to apply them. You are almost there.
