First, to assume that complex animals such as dinosaurs came from senseless and intentless
evolutionary processes is not ignorance it is willful stupidity.
To assume that complex animals such as dinosaurs came from intelligent and intentful processes is nothing short of anthropomorphism.
Second, to say that somehow a comet hit the earth and killed all of them and then evolution readjusted is vain speculation.
Firstly, it wasn't a
comet that hit the Earth, it was an
asteroid. Comets are made mostly of ice, so the comet would've evaporated because of the heat of it burning through the atmosphere, thus
not leaving the huge crater. Second, saying "evolution readjusted" is meaningless, since evolution is a constant process for life on Earth. Evolution
always happens, regardless of whatever catastrophe may decrease the population of organisms on Earth.
Evolution theory is a loop-hole for people to throw off their accountability to the Creator.
A popular myth which is commonly being spread by Creationists. Only those who
want conflict between evolution and "theism" are going to see how evolution and theism conflict.
There is talk that the Dinosaurs evolved into the birds. This is an incredible feat for random mutations to accidentally make. Evolutionary theory makes something complex look simple. Simplifying the creation is the only thing that makes evolution even half plausible. Anyone who is willing to do the unbiased research should see that we live in a very complex SYSTEM that could of never come about through mindless evolution.
You do not understand evolution. Evolution does not work purely through random mutations. There is natural selection, and, thus, there are selective pressures which allow for mutations. Considering the harsh, cold climate which pervaded the Earth following the asteroid impact, it's fairly easy to see what selective pressures were involved in dinosaurs evolving into birds.
