Big Bang theory is not valid.

[popeyespappy]

It is in fact moving, but expanding from where? for something to expand it needs a point of origin, there is no suggestion it is expanding, the universe is in constant motion that has been obvious from day one considering our solar system.

Once again, your misunderstanding of the Big Bang has led you to making false assumptions. According to the Big Bang model the universe does not in fact need a point of origin. According to the Big Bang model expansion is happening everywhere. Space is expanding everywhere in all directions. This is why the distances between the galaxies are increasing. This is supported by our observations.

Now before you go off on a tangent and explain to us that this is obviously false because the Earth, our solar system and galaxy are not expanding there is something else you need to understand. Locally gravity has overcome expansion and is holding this matter together relative to the matter around it. With some localized exceptions the distances between galaxies and groups of galaxies is growing.

The exceptions are instances where objects are moving towards each other at velocities greater than the rate of expansion. We are part of one of these exceptions. The Milky Way and Andromeda Galaxies are moving toward each other and will one day collide. If I could choose how long or when in time I would live, I would choose to be around to watch the night sky as we approached Andromeda and the galaxies collide. That would make for quite the show.
