In the beginning was nothing.
The human mind cannot conceive the imagery. We can visualize life before human existence or life before the earth came to be, but what about before the singularity? Nothingness surrounded by infinite nothingness. How can you comprehend it when there is no starting point? How far back can you go in time? Cosmic censorship prevents it. Naked singularity has yet to be observed. All you have as evidence is cosmic echo in the backdrop of space. Leftover relic radiation of what once was.
The birth of the universe is analogous to your own.
