"In the beginning God created the heavens and the earth".
But did he do it as related in Genesis, or by a Big Bang, or what?
And is "God" a conscious being, as various religions believe, or some kind
of impersonal force like gravity or electricity?
If the Bible had stopped at those ten words, it's as good an explanation as
any.

Something had to start everything, unless there never was any beginning and
things have just gone around in circles.
What happened before? There wasn't a Before.

Why worry about it? Here we are on Earth, until our species becomes extinct
altogether.

I don't remember where I came from, (if anywhere) and I don't know where
I'm going afterwards, if there is an "afterwards" for me, though people have
made various guesses.

"A bird flies into a lighted hall and flies out again." Wasn't it Bede who
said that?

I'm still none the wiser, but I'm overdue to fly out again, so I shall find
out. Or not!
