I’m reading Stephen Hawking and I understand about 0.052 percent of what he’s saying, but have a few questions that I think will help me understand a lot more of what the big bang is about.
1. My understanding of Hawking is that scientist based the big bang theory on the fact that the universe is expanding. To me that’s very big leap. . How did they get from the phenomenon of an expanding universe to the conclusion that the universe began 10 to 13 billion years ago? there are so many variables that have to be taken into account to make such a calculation—the rate and duration of periodic accelerations, the effects of gravity on acceleration, the effects of collisions on acceleration
2. Is the Doppler Effect the only evidence scientists have that the universe is expanding?
3. How do scientist know what size the universe was when it started expanding? We cannot say how long it took to get from point A to point B if we don’t know what point A was.

The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.

Nietzsche isn't dead. How do I know he lives? He lives in my mind.
