You can use either Occam's razor or anthropic principle.

No, I can't. I know the difference.

Thank you for your reply!

No, I can't. I know the difference.

I never said you didn't. That was an "either" "or". IOW, either assertion is used to assert metaphysical naturalism (atheism). From my post at 1902:

You can use either Occam's razor or anthropic principle.

The bottom line is that to a person whose worldview of reality ("all that there is") is that which occurs in nature - the arguments are equally asserted to rationalize the metaphysically naturalist (or atheist) worldview. For instance, that God is an unnecessary hypothesis - or that physical laws and constants had to be the way they were for physicists to identify them - or that someday a physical explanation will be given for everything.

From infidels.org on - the atheist web - common arguments:

William of Occam formulated a principle which has become known as Occam's Razor. In its original form, it said "Do not multiply entities unnecessarily." That is, if you can explain something without supposing the existence of some entity, then do so.

Nowadays when people refer to Occam's Razor, they often express it more generally, for example as "Take the simplest solution".

The relevance to atheism is that we can look at two possible explanations for what we see around us:

There is an incredibly intricate and complex universe out there, which came into being as a result of natural processes.

There is an incredibly intricate and complex universe out there, and there is also a God who created the universe. Clearly this God must be of non-zero complexity.

Given that both explanations fit the facts, Occam's Razor might suggest that we should take the simpler of the two -- solution number one. Unfortunately, some argue that there is a third even more simple solution:

There isn't an incredibly intricate and complex universe out there. We just imagine that there is.

This third option leads us logically towards solipsism, which many people find unacceptable.

The solution number one can also be stated as the anthropic principle as excerpted in post 1919
