An unorthodox belief in God.

[Fidel_Castronaut]

No, things in our reality are too deliberate , the earth was obviously well suited for humans.

This is a classic fallacious argument contained in a thesis of fine tuning.

What % of the Earth exactly is well suited to humans? I think you'll find if you do a statistical analysis of the total surface area of the earth, a tiny % of it is actually habitable.

It's also looking at the equation the wrong way around. Humanity (indeed, every species) has evolved to the environment in which it inhabits (or finds itself inhabiting). Those that do not, die out. We have evolved lungs to breath a nitrogen rich oxygen atmosphere, not had a nitrogen rich oxygen atmosphere put there to suit our lungs.
