> Earth lifetime is nothing on the grand scale of things.

Nit: Isn't the estimated age of the universe 14 billion and earth 4.5 billion? I wouldn't call that nothing.

> The universe could possibly avoid eternal heat death through random quantum tunnelling and quantum fluctuations, given the non-zero probability of producing a new Big Bang in roughly 10^10^10^56 years

I used to explain to myself what was before the universe - that it simply didn't exist, just like myself didn't exist, but in fact my body is a continuation of life since its inception - like my parents knew their parents (or at very least they had a brief contact with their mothers), their parents knew their parents and so on back to something that sparked life, but that something also must have come from something. So still can't get my head around what was before the universe. I know these visualisations that show for example that something that has beginning and end can be divided infinitely, but when I picture it, this exists in some sort of space.
