You CANNOT prove that humans evolved from monkies. Observations INDICATE, but the evidence is still lacking.
Evolution is a THEORY.
You cannot prove the existence of god. You cannot prove that god created all life on earth.
ID is a THEORY.
Scientists are SUPPOSED to be open to all possibilities.
BTW - Atheism IS a religion. Just because they deny divinity that doesn't make it any less of a life philosophy. Scary as it is, because it's not considered a religion, it is taught in our schools....:(:(:(
That would be B4.
Noone says that humans had evolved from monkeys (that I can recall). Evolutionists do say that humans and monkeys evolved along separate paths from and at one point there was a precursor animal to both of them.
As far as proof, you need to be very careful on your definition. Every mathematical and scientific theory is built on axioms (unproved assertions). Such as the definition of a line or of a circle (for mathematics). I think it is unreasonable to throw out all axioms, because then the words 'scientific proof' would have no meaning.
Additionally you will need to define a probability that says where a theory is reasonable or unreasonable. Scientists typically do this with the standard deviation of a number and line fits (such as χ² if you are familiar with that notation). By these methods you can say that if you repeated the observations randomly, there would be a certain percentage probability that they would fall within various ranges from what the theory predicts. This is the modern method of a scientific proof. You don't say that something is 100% certain, you say it is 98.353% certain, and you list your sources so that people can critique you and re-perform your calculations to make sure you are correct.
I would argue that based upon the above considerations, that the theory of evolutions has been proved to a certain level of confidence.
Evolution is a theory, a well-suported and tested body of observations. ID is a hypothesis, a wishful guess. Learn the difference.
