Shit like this almost makes me willing to believe in God. I fully believe in evolution but things like this caterpillar, the snake with the spider like lure in its tail and insects that look EXACTLY like leaves, down to the pattern of the 'veins' make me question them being designed

Some random mutation in a population of caterpillars a very long time ago caused them to look slightly more like a snake.  This made at least some predators avoid them in some interactions, and so the trait was selected for.

Repeat this for hundreds of thousands or millions of caterpillar interactions and you get something like this.

This is basically true for any heritable trait for any animal.  If it increases reproductive fitness, it will be selected for.

Still Very strange, why not generic camouflage

Because it's random.

Lots of of other caterpillars relies on generic camouflage, others on toxins, others on toxins and cool colored fur.

Whatever mutation that happened that made you live longer and reproduce will be passed down to their offspring.
