I have space here only to glance briefly at these opinions. But, of course, the objector means, no doubt, that the whole universe is just a coincidence. Frankly, it's easier to believe in a Creator God. The human mind can at least begin to cope with Him. Furthermore, total coincidence would make science impossible.
All science depends upon the researchers' ability to replicate experiments.
No predictability - no science. It isn't a serious view. You needn't fear death. The result of that disobedience and independence from God is the mess were in. And if you would wake up and look around you at the way the world is, you would be insecure, too.
