The singularity is the centre of the spacetime, not its beginning?

Why mainstream science doesn't consider the option that the singularity is the centre of the spacetime?
For me, it seems logical. Asking "what was before the Big Bang?" is like asking "What is under the Earth's centre?" So, spacetime spreads in every direction from the Big Bang.

Are there any significant reasons why do we need the concept of "the beginning of the spacetime"? Moreover, the concept of "creation from nothing"?

Big-Bang-ists claim that time itself began at the singularity. However describing the big bang as an "explosion" or "spreading" is in itself problematic: The not-space. Some questions.

@kiwiheretic, good question.
I don't know how the mainstream physics answers it, but here's my personal opinion.
"Space" is only a math abstraction in order to describe the real world, as well as numbers. There are many different spaces: Euclidean space, Minkowski space, Riemann space and so on. We can apply these models to describe matter, energy and relationships between them. But no one has never observed "space", only matter and energy. When they tell "space expands" or "space curves" it's only a convenient model.
