the theory of gravity can't be proven either.
No scientific theory can be proven.
Why do you make points that are obvious? Will you tell us next that noone can make a 3 sided square?
Why do evolutionists continue to attack and bludgeon Creationists if neither "side" can prove their world views? The answer is simply this: Evolution is allegedly the antidote to Christianity, and the secularists, in their never ending quest to purge morality from society must first kill the originator of Morality.
It is so much more easier to slaughter children in the womb if the biomass inside a woman is not human life. It becomes much more easier to exterminate people groups from the earth (ie, Jews, the unborn, old people, the terminally ill and deformed) if we are all animals of the same level as beasts and bugs. It is much easier to enslave people to a State government if mankind is not a special image of his Creator, but is simply an accident of Chance.
Evolutionists are on a desperate quest to dehumanize mankind. Environmentalists will say that mankind is simply a destructive animal, and thus will reverse God's command for man to dominate the earth by claiming that man is subservant to the earth because man is nothing more than a temporary accident of Chance.
Feminists will come forth and reverse the hierarchal order because both females and males are accidents of Chance not special creation from the hand of a personal God.
Because mankind is an accident of Chance, some species of man are more human than others, which makes it perfectly fine to incarcerate aboriginals in zoos and make lampshades out of others.
Does this make sense to you?
