Is there objective Truth?

[Angrboda]

After all other options have been rendered impossible, what remains is the answer.

You haven't rendered all other options impossible, only those options known, so this remains an argument from ignorance.

The natural world cannot justify its own existence.

You were asked to explain what you mean by this already. If you're appealing to some extreme version of the PSR then say so. Otherwise this is just a strange and unrelated claim. What does it mean to 'justify' the existent?

Absolutes, moral duties, immaterial laws, work much the same way, demanding a trancedent cause. Something above and beyond the natural order

So you claim. I need more than just your claim to believe you. So far all I have from you is an argument from ignorance and a just-so story.
