How Did Everything Get Started?

I sometimes wonder how everything got started; the universe, I mean. How did it all start? Scientific orthodoxy nowadays says the "Big Bang" is what started everything. The Big Bang is an expression coined by astronomer Fred Hoyle to make fun of the theory. Hoyle thought the Big Bang was pseudoscience. There are scientists who disagree with the Big Bang, even today, they have other ideas.

I have to say that when I try to imagine that infinitely small point of heat and energy required by this theory, I just can't wrap my mind around that. My common sense says "no way!" How can something be infinitely small? It's just ridiculous! How can something be nearly infinite? That doesn't make sense. How can something so unimaginably small contain what is necessary to build a universe so unimaginably huge? Again, it makes no sense.
