That's unproven. And the Big Bang is almost a certainty. Between the cosmological redshift and the CMBR, it's incredibly likely that both A) there was a big bang, and

the universe is still expanding. And since there was a big bang, there is a start point to time, and that was ~13.75 billion years ago.
you havent been on your current events in the astronomy world. we are finding the composition of more and more galaxies with high redshift to have heavy metals (impossible according to big bang). we are finding that the opposite is also true (no redshift galaxies with no heavy metals). as for the CMBR: nothing can travel faster than the speed of light, so there is no way heat radiation could have traveled between the two horizons to even out the hot and cold spots created in the big bang and leave the thermal equilibrium we see now.
an assumption ive always wondered about: they say lighter elements make up the first galaxies because intense pressure inside a star is needed to create heavier elements. if the big bang was a singularity shouldnt there have been adequate pressure to create them when this first singularity exploded?
