Here is a very brief, but profound answer by Graham Hancock.

Good video and sounds correct to me, Could have listened to some more, Pity it got cut short.
Cheers for the link.
Link worked fine for me,
I believe we "humans" get hung up to much on time/distances,
To me billions of years is just a blink of an eye, We have tried to define time and by doing this we have boxed it, All time exsists in the moment, as there is no beginning and no end,
We has conscious beings created everything when we became aware,
>Consciousness>universe>life>consciousness>universe>life>consciousness>universe>life>consciousness>.......
We search for a beginning but there is no beginning, only a continuous cycle.
Everything exsists within everything.
We just have to look past the restrictions we have placed on ourselves.
We are "human" but we each contain untold universes, we are like russian dolls everything within and without, our consciousness gives us form in this "world" we share, We do not die/decay, we are continuously expanding in every direction, When we have expanded to the next level our consciousness leaves this "human form" and takes up residence in our newly expanded form. It is a continuous cycle.
