I have been thinking about the Big Bang again. As you do.

I noticed the other day that Richard Dawkins quietly said [in hope that no one would ask him to explain, because i suspect he doesn't know what this means] that the original universe came from nothing by a 'quantum fluctuation'.
a quantum fluctuation can be defined as;

In quantum physics, a quantum vacuum fluctuation (or quantum fluctuation or vacuum fluctuation) is the temporary change in the amount of energy in a point in space,^[1] as explained in Werner Heisenberg's uncertainty principle.

Now, a change in what energy? you cant have a change in something that didnt exist. there was nothing before the big bang.

Another point, if nothing existed before the big bang, where was the geographical location of the quantum fluctuation? There simply wasn't any place in which the fluctuation could occur.
