How come that you exist? Isn’t it odd that we exist? We aren’t supposed to but we do.

All the religious and scientific reasons have to accept a starting point to answer our existence. That starting point may be the Big Bang or a superior being that has created the universe and life within it.

But why do we have to “accept” a starting point? There must have been something else before them that caused their existence or did they born from NOTHING? But how could someone accept that a car would just pop into existence out of nowhere.

I exist because of my parents, and they exist because of their parents. The cycle continues and ends at a point where we cannot further go back but have to accept that all things came into existence from a “starting point” and we don't know why and how it was there even in the first place.
