I'll start with one of the last points first.
Atheism (at least, not all atheism) is based on non-answered prayers, the problem of evil, and an irrational hate for religion.
I was a committed Christian before, and I fought my doubts for years before I finally lost faith and accepted I was an atheist. This wasn't an easy thing for me... God meant SO much to me, and I begged God to show me a sign.
I lost faith because I no longer saw good reasons to believe. At the arguments are faulty and have gaps. I used similar arguments used in the video when I was a Christian.
---------------
My position on what happened in the beginning is that I don't know. It's very hard for humans to conceive of what is possiby beyond time, and beyond our universe. I do have ideas though.
If you think God is possible, then I suppose you could accept that other timeless states could exist too? Perhaps a simple timeless states allow various universes to pop into existence. ie: Instead of a timeless God, there is a timeless state of reality.
Another thing to consider is that if the universe was a singularity, and that means the universe was timeless at time zero, then there was no time when the universe didn't exist. That isn't to say the universe is eternal, but rather to say that there was never a time when there was nothing, and then the next moment there was a universe. At all times there was a universe because time is part of the universe.
What we are looking for then isn't a cause to make something from nothing, but rather an explanation for why there is a universe rather than nothing.
The videos says that we have observed that nothing does nothing, but then goes on to say that the vacuum is still something. I'd say that we have never observed nothingness then.
The video also says scientists create hypothesise not based on evidence. On the other hand then the god idea isn't either. If it's possible that other explanations could be true, then there is no reason to be theist (or deist).
Another point made is that of fine tuning. I'd say multiple universes or some Theory of Everything we don't currently know could explain the laws.
Finally, I dislike religion because it is false, and also because it gets good people to do or support bad things.
