Of course ignore the actual proof, aka cosmic background radiation of the big bang that has been mapped as well.
The problem is not so much the Big Bang, but the early expansion physics. For example, the universe shows superstructure at the largest scale. The current theory of the universe, has space-time expanding at all points, simultaneously, like a balloon blowing up. It did not expect or predict the less than symmetrical superstructure. A different early physics mechanism is needed.
Besides the superstructure, there are spiral galaxies with too many turns, so very early in the universe. Like the rings of a tree we can age spiral galaxies by their number of turns. These ancient spiral galaxies are too advanced; old looking, for being in the universe so early. Physics need a new mechanism to explain this, since the current early physics falls short.
Stars are being found that also formed very early, compared to the current early physics predictions. Big Bang is still fine, but after t=0+, is now very shaky. Change to theory is slow and students are left defending a sinking ship.
I proposed a model that can fix this almost twenty years ago. Picture the primordial atom of the BB, being similar to the mother of all black holes. Space-time is highly contracted, so it appears as a singularity. There is no event horizon since even that is part of the point.
The current model has this suddenly expanding into umpteen particles. This would represent a huge increase in entropy, which absorbs heat. This is where observations like early stars and galaxies have a problem. One would need to go against the second law; quickly reverse the hot atomization, to make structure.
The work around is the singularity for the BB does not directly atomize into particles, but rather it splits like a mother cell into two daughter cells. This will also increase entropy, but much less, thereby needing less energy to occur. It is also causing space-time to expand, but much slower, since we still have two close black holes.
In this model, the daughter cells continue to divide, again, and again, as energy is made available; body of the universal superstructure. When we reach a critical stage; matter condensation occurs at the level of the smallest daughter cells; galaxy scale. Now there is a mini-big bang phase cascade, at the level of the galaxy cells. This expansion of the daughter cells, explains why the universe appears to expand relative to the galaxies and why galaxies have huge central black holes; remnants of an earlier time.
With all these daughter cells very compact, when the Big Bang or mini big bang cascade starts to occur; billions of little time bombs, all giving off powerful energy wave fronts, as the galaxies expand relative to each other. Pressure waves from all sides and gravity keeps galactic matter close to the central daughter cell, and external turbulence adds eddies. The universe's body is roughed in very quickly by modern standards.
