Difficulty IS how do you prove that a space contains nothing. Some scientist tried to convince us that there was this mysterious gaseousy thing called 'the ether' left there when you took away all the air. However we know that we cannot detect some things until a detector is invented cf radiation and Magnetic waves also gravitational waves. Remember matter and energy are interchangeable - although I do not fully understand that phrase. So things can change form from invisible to visible and vice versa.

What is your definition of nothing and what is your definition of everything?

The videos logic is that there is God.....cause colors and grass and sky and form or some type of cohesion. I can say there is tooth fairy.....cause teeth, or there is Bigfoot.....cause hair and bipedalism. They take a giant leap of faith. No surprise. The narrator either just nitpicked bad arguments from people or planted them in the film.

I think the real problem here is what we call nothing may not really be nothing just like in quantum mechanics when particles pop in and pop out of existence. Maybe some of the stuff comes from another dimension? Plus scientists talk about a singularity that's a ball so heavy it would contain a lot of stuff and then elements change and expand? Anyway I'm not a theoretical physicist, but I like reading about all that stuff.

Short answer - there was never a time when there was nothing, and there's no reason to think everything was created.
As for Ray Comfort videos, he's been caught out with his dishonest interview video editing before, so I wouldn't trust anything he makes.

Energy created everything so much of it it exploded and when it cooled down matter was created . That’s the simplified version

Another universe/dimension (for lack of better terms that our brains can comprehend) appears to be nothing from the point of view of this one.

Ugh.... Banana man Ray Comfort..and shared by Feuerstein... sigh... double whammy. brain hurts now.
