It is a view that many take and it has more proof than you offer. Just saying something was there neither identifies what it was nor how it got there.
Your asking people to take it on faith that it was always just sitting there for a googolplexian, before it decided to detonate without any action of outside forces because it was the only something. Then the dot expanded into the entire universe which just happens to be flat and round. Because a googolplexian of years of equilibrium changed because of the action of what? It cannot change by itself. It would have required an outside force.
