I find this interesting for many reasons..

We, people/all life as we know it, seems to be pre-programmed for quite a lot. I can elaborate if needed, but I'd rather leave here if possible.

To slightly build up on the previous: Is it possible that we do happen to carry over some knowledge of the previous? Knowing the bare-minimum, essentially running in autopilot, is extremely beneficial for the success of life, especially at birth/conception.

I want to know, what happens if we no longer have a physical realm? It is believed that life on earth will be impossible one day. We have more unknowns than knowns when it comes to the universe, but all science points to the earth no longer being capable of sustaining life. If we are incapable of escaping the death and destruction, do we also cease to exist in any realm?

I also am curious to know, do you consider all known life to also stem from the same entity?
