Did energy begin to exist? Can energy exist without space and time?

Did energy begin to exist at the Big Bang? Can energy exist without space and time?

Or don't we know?

When I've tried to research this I get a mix of different answers. I have virtually no understanding of science or physics in general FYI.

Well, first you have to define what you mean by energy.

You can start with the basics. It is not a thing. It is a number.

The notion of something "beginning to exist" before time exists is something of an oxymoron. You'll have to put your question on much firmer footing before it can be answered.

The Big Bang was not the start of the universe. Whatever a "start" is is not even defined. It would be a discontinuity of time.
