Science, Religion, and the Big Bang
Why Physics Stack Exchange recommends it
Physics Stack Exchange users link it to correct the common picture of the Big Bang as an explosion at a single point, and to explain that expansion happened everywhere.

What it is
A five-minute MinutePhysics whiteboard video by Henry Reich on what the Big Bang theory does and does not claim. It argues the Big Bang was not an explosion from a point but an expansion happening everywhere, and touches on how science and religion relate to the idea of a beginning.

This is the best visualization of the big bang theory I've seen. Check it out, as it may clear up some misconceptions [this video]

I think Henry made these two minute physics videos( Where Was The Big Bang? [LINK] and Science, Religion, and the Big Bang [this video] ) specially for you: As a short answer, the big bang happened everywhere! So anyone, anywhere(to be super cautious and conservative in an inertial frame) can say I have been at the center of the Big Bang :)

The answer to this questions turns out to be a "yes" . The big bang is a sudden rapid expansion of space, so yes, there was space before the big bang. To understand more, check this vulgarization video [this video] by MinutePhysics who corrects some misconceptions about the BB, since you seem to not know the Friedmann-Walker-Robertson-Lemaître metric.

Hey @Chris Lovell I must ask you to watch this video [this video] after reading your answer. You have tokened singularity, but many still say that there was space existing before Big Bang.

Recently I watched a minute-physics video [this video] that suggested that a better name for the beginning of time would be "Everywhere stretch" because there wasn't a space-time singularity that formed where the universe began to expand but the expansion happened everywhere. Well, if the expansion did happen everywhere that means that space and stuff had already existed. So what would happen before that expansion and why cant we see it (why don't we receive any signals? In the end, as you can see, he brings up a theory that cannot be excluded, which suggests that the beginning of our universe was the end of another because of the Big Crunch, the collapse of space on itself. If that's true how th

You seem to be misunderstanding what inflation does. Lets say the entire universe is two stars and those two stars are gravitationally attracted to each other, but space is also expanding between them so the stars move apart from each other. Both stars happened inside the big bang, and as they move apart, the space between them that inflation creates happened inside the big bang as well. Inflation doesn't happen beyond the big bang, it happens inside where the big bang happened. It could also be said that the big bang is inflation, at least, that's what it is as far back as we can tell what it is. (I hope my layman's explanation isn't too far off).

Some good questions. The center of the observable universe is you. The big bang (or everywhere stretch), happened everywhere but to the observable universe, you are the center and, so am I and so is he and so is that star way way way over there. [this video] and similar question here. [LINK]

The biggest hole in your argument is the following: "by the theory at first it was finite." This is perhaps one of the biggest misconceptions about big bang cosmology that exists. The big bang theory, as it stands today, merely notes that, at some point in cosmic history, the universe was very dense. This does not imply finite-ness nor does it imply that the universe started "at a point," as so many like to say. The standard model of cosmology simply states the following: Assume I have two objects that are both at rest and are a distance $d$ away from each other at some time $t_0$. Then at a time $t$ they will be a distance $a(t)d$ away from each other, with $a(t_0)=1$ by definition. By mean
