It was dark... They were big, and they were wearing masks and didn't say anything! I was dragged out of bed, they sat me in front of my computer and logged me in here. I was helpless, helpless I tell you! None of this is my fault!!
Yes! I was predestined from the moment of the Big Bang to be here typing these very words.
The Big Bang took place. Atoms and elements were formed. The atoms interacted and reacted with each other, formed molecules, etc. according to the blind laws of physics and chemistry. These reactions inexorably drove the evolutionary process. There is no freewill that could alter or circumvent these lawful reactions. Hence it is this chain of atomic and molecular reaction that has led inevitably to my typing of these words here. No other outcome was possible.
[Note: the above is not actually something I personally believe, but seems to me to express an extreme form of materialist determinism.]
