Is atheism a scientific perspective?

[Chas]

And I don't think that you can just credit the crowning achievements of biologists to the theory of evolution. The fact is that the theory results in many similar predictions that one would make from design. We also don't know how quickly science would progress if people had design as their point of reference. It may be faster.

The theory of evolution explains complexity in a simpler fashion than does your idea of design. It does not require a designer.

You have no evidence of a designer. Until you do, your argument is specious.

Again, you don't seem to grasp how evolution works.

Do you think that poor diet/lifestyle has a genetic basis that is acted upon by natural selection?

It absolutely does,

Unsupported assertion.

but that's not even what I was trying to convey.

What were you trying to convey?

We are less susceptible to diseases and infections if we eat plant based foods and exercise.

Unsupported assertion.
Eating meat is a more efficient means of nutrition than a purely plant-based diet. We have evolved as omnivores.

Therefore, those who do not live this healthy lifestyle are more likely to be removed by the purifying force that is infection. At least this is a possibility.

Purifying force? Are you serious?
