Big bang didn't happen in a single point in our space-time like a firecracker, it happened everywhere and was just a uniformly much hotter and denser universe that didn't really explode into anything, but space-time just expanded to make the universe less dense.

Don't some people prefer to say the slow expansion over using the term big bang? Although it hasn't taken off as a term. Or something like that?

If “everywhere” is an infinitesimal point, is there much difference?

Everywhere was not an infinitesimal point, if the present Universe is infinite (as it seems to be). In this case, the Universe was already infinite at the very first meaningful instant of time.

To be more pedantically precise:

The big bang was not like a firecracker that went off in pre-existing, infinite flat space-time...

There are two replies to my comment, yours and someone else's. They both say the opposite thing!
