We know all galaxies spread out after Big Bang theory.The key idea is that the universe is expanding after that theory. Can we play back the scenes via observable universe (galaxies) and can we calculate the coordinate of big bang point as a fixed reference point in the universe?

Is there a such calculation in literature or claim?

EDIT: After answers I have some questions:

If the distribution of matter in the universe is homogeneous,how should we think the geometry of universe. Is it a sphere ? Does not a line go to endless as we imagine? Is there any idea of the border of observed universe? If the universe is homogeneous and like sphere geometry, can we see the beginning of our baby galaxy while observing in the sky?

I really will appreciate if someone explains what the universe geometry structure is if we have a homogeneous universe after big bang.

Thanks

It is not possible to calculate the coordinates of the point where the Big Bang happened, because there is no such point. All of space is expanding away from the rest of space, in a manner that looks the same throughout space (the technical term is that the universe is homogeneous). The Big Bang happened everywhere in space.

The Big Bang happened in every point of the whole volume of the Universe. We don't have to calculate the point - it us everywhere. Every single point (your finger tip, your bathroom, center of Mars, center of Andromeda galaxy, everywhere) experienced the inferno of the birth of the Universe.
