Hi nipok
So you think that we live in an infinite space where Big Bangs are occurring all the time (and in this case - each Big Bang is simply an explosion producing matter)? And we don't see these Big Bangs because they occur outside of our visible Universe?
Why then does the Universe look different the farther away we look?
Why do we see such large scale homogeneity in the visible Universe?
What's the mechanism for how these "little bangs" occur? In an infinite universe why are these bangs likely to occur where they do and not somewhere else?
If one of these little bangs occurred in our solar system right now, would we know about it (i.e are these universes connected)?
Space (or spacetime), the backdrop upon which matter and energy "sits" has physical properties of its own (e.g matter can warp it). Where did this space and its properties come from?
One of the little repeated but obvious issues with an infinite universe is that it allows for an infinite number of possibilities. As long as something is physically possible, the chance of it happening in an infinite universe is 1.
This means that there are an infinite number of doppelgangers of yourself for example. Weirder still, there are regions of the Universe where the probabilistic laws of the quantum world are actualised at a macroscopic level.
Somewhere in an infinite Universe, Saddam Hussein has walked through the wall of his prison, evaded capture, quantum tunnelled through the Earth and ended up in Washington to poke Bush in his eye, for example.
This is a pretty outlandish consequence - is this what you believe to be happening somewhere?

PS You know its never really been proved to my satisfaction that the earth is not supported by invisible rotating turtles, but unless I can use turtle theory to explain all the data currently explained by Big Bang cosmology and GR, its of no use to anyone. Yet.
