Can something come from nothing

[pocaracas]

For example:

Fallacy of composition. Everything in my bag is blue; it doesn't mean my bag is also blue.

You can't make something blue using only red LEGOs. Likewise, you can't make something out of a whole lot of nothing (which is pretty much all you have, Rob).

What if the philosophical nothing was never a reality?
Sorry, faulty wording, as nothing would preclude time itself from existing.

But what if time and space have existed for a past infinite? A past beyond the big bang, beyond the known barrier to information about that past...? A past unknown and, as far as we can tell nowadays, unknowable.
