I get the impression you don't understand the concept of the Big Bang when you say "perhaps millions of Big Bangs that created the galaxies, stars and planets that we see in the universe today." That's now how the theory works. The idea is that ALL MATTER of the entire universe appeared in a single Big Bang event when the universe exploded from a singularity. It doesn't make any sense to talk about many "Big Bangs" within an existing universe. It is the universe itself - the entire space-time continuum that contains all matter - that began as a singularity which "exploded." The galaxies, stars, and planets formed a long time after the Big Bang. Here's how the wiki describes it:
After its initial expansion from a singularity, the Universe cooled sufficiently to allow energy to be converted into various subatomic particles, including protons, neutrons, and electrons. While protons and neutrons combined to form the first atomic nuclei only a few minutes after the Big Bang, it would take thousands of years for electrons to combine with them and create electrically neutral atoms. The first element produced was hydrogen, along with traces of helium and lithium. Giant clouds of these primordial elements would coalesce through gravity to form stars and galaxies, and the heavier elements would be synthesized either within stars or during supernovae.It's fun to speculate about modern physics, but we should start with a solid understanding of what the theories actually state.
