I disagree that the big bang is implausible. I concur with Stephen Hawking on this subject.
Stephen Hawking, in his final book, argues there's no possibility of God existing because time didn't exist before the Big Bang.

To Hawking and many like-minded scientists, the combined laws of gravity, relativity, quantum physics and a few other rules
could explain everything that ever happened or ever will happen in our known universe.
"If you like, you can say the laws are the work of God, but that is more a definition of God than a proof of his existence," Hawking wrote.
With the universe running on a scientifically guided autopilot, the only role for an all-powerful deity might be setting the initial conditions of the universe so that those laws could take shape — a divine creator who caused the Big Bang to bang, then stepped back to behold His work.
"Did God create the quantum laws that allowed the Big Bang to occur?" Hawking wrote. "I have no desire to offend anyone of faith, but I think science has a more compelling explanation than a divine creator."
"The universe itself, in all its mind-boggling vastness and complexity, could
simply have popped into existence without violating the known laws of nature," he wrote.
That still doesn't explain away the possibility that God created that proton-size singularity, then flipped the quantum- mechanical switch that allowed it to pop. But Hawking says science has an explanation here, too. To illustrate, he points to the physics of
black holes — collapsed stars that are so dense, nothing, including light, can escape their pull.
Black holes, like the universe before the Big Bang,
condense into a singularity. In this ultra-packed point of mass, gravity is so strong that it distorts time as well as light and space. Simply put, in the depths of a black hole, time does not exist.
Because the universe also began as a singularity, time itself could not have existed before the Big Bang. Hawking's answer, then, to
what happened before the Big Bang is, "there was no time
before the Big Bang."
"We have finally found something that doesn’t have a cause, because there was no time for a cause to exist in," Hawking wrote. "For me this means that
there is no possibility of a creator, because there is no time for a creator to have existed in."
