The beginning is the end is the beginning?

It's curious to think about the concept of creation. How the universe came into existence, why it came existence..
I find it preferable, not to mention comforting, to think that maybe nothing exploded at all. Maybe there was no Big Bang, or a lotus flower that opened up to give birth to Ra. Maybe nothing began.
What if, like the forever symbol dangling from a piece of black string on my wrist, everything is continuous?
Yes, we die, but the state of our consciousness, our chi, does not have to simply end. Maybe in an eternal cycle of being, we are transferred into another body, a host that, due to lack of mental capacity at the time of birth, causes us forget the previous life that we had lived.
Even if I were to become an insect, the concept of reincarnation is an idea I am willing to entertain.
I would like to remember this life though, to keep my memories as I continued to exist as someone or something else.
As for the question Why are we here?, is there any reason for us not to be?
