evolutionists need to really expand their vocabulary. evolution could mean anything from a caterpillar/butterfly, to a dog breed having better smell, to deer being created from zebras, and becoming their own species. i call the last speciation, and there is no evidence to prove speciation. there is evidence supporting speciation, and evidence against. so many dogs are so different, yet no speciation or even a single new piece of genetic information arises? nobody has ever witnessed, or created a new species. mixes of 2 species cannot even provide a fertile animal. (like a mule, being a donkey and horse, has NO sexual interest or capability)
DNA similarities is definitly a fact.
How that happened is not evidence, because the reason of why they are similar is a guess. you can say a chimpanzee has similar DNA to you till the cows come home, but the reasoning behind it is pure speculation. speculating its because God made it that way, or because nature made it that way, is completely based on opinions and faith.
I believe the whole idea of seperating evolution from a possible theory, into a "fact" is because all theories and personal beleifs require faith. Faith is a terribly cold thing to have. having to question your core beleifs, and consider the possibility that your wrong ? who wants that, when you could just convince youreself its a fact.
