Argument #1: Transitional Fossils

[Mister Agenda]

However that hypothesis can be eliminated due to the fact that 99.8% of all of the species that have ever lived have now gone extinct.

In other words - the level of intelligence evidenced in the design is too low to be worthy of consideration.

Unless your God is dumber that a bag of dead squirrels, that is.

I highly doubt the level of intelligence of a species will decide or not if they become extinct. I also don't understand how extinction supports evolution?

Nature is indifferent to the survival of species, hence a high rate of extinction. If an insufficient number of individuals within a species are able to pass on their genes, the species goes extinct. It could be just bad luck, like a species that only lives on one side of a particular mountain and is wiped out when the mountain turns out to be a volcano. Other species are also part of the 'reproductive fitness landscape' of a species, extinctions alter the course of evolution.
