> but pre-big bang is hard to conceive It's like trying to imagine what is it like to be before you were alive. You simply can't. Its not really a valid question. There was no time before big bang. So we as humans cannot have a frame of reference to even begin thinking what was before.

That is not to say there wasn't anything (say we as 3D being are unable to experience/imagine 4D).

Another way of putting it is that every person alive today was dead for 13 billion years before being conceived and born, and will (relatively) soon be dead for however long the universe exists.

can you prove that?

(sorry, not talking about religion or life-after-death, just about how you go about proving something that can only happen outside your experience, and you have to rely on secondary evidence to deduce it)
