The Two Eternities:

Each individual life is but a flash of light between two eternities of darkness.

-Ella D'Arcy, The Web of Maya

The first eternity is the time before conception. The second is the eternity after death. But I'm not sure the eternities are dark. There is starlight for a good long part of both eternities. 

I wonder which eternity is longer. Supposedly, a really long time ago there was a big bang and an expansion of the universe. Will the amount of time that has elapsed since the big bang until now be greater or less than the time from now until the universe collapses into itself?

Was there really an eternity before my birth? Has the universe cycled forever between expansion and contraction and only during this most recent contraction was the earth and human life created?

Some infinities can be greater than others. We know that from The Fault in Our Stars by John Green. There are an infinite number of moments between now and tomorrow as there are between now and next year. But the infinity of moments between now and tomorrow is less than the infinity of moments between now and next year.

The trick is to be grateful for the little infinity that we get.
