Has there been ANY proof that any life form has “evolved”?
Scientists don’t really ever “prove” anything. It is mathematicians who do that. Scientists just make hypotheses and then try to test them by making predictions based on them that can hopefully be confirmed with experiment or observation. Even if they are confirmed, they still are never “proven”. There is always the possibility that a better hypothesis could predict the same things and also form a more complete or accurate theory.
At least, that is how science is supposed to work. There are some scientific disciplines where that method can’t be easily applied, so they may play a little looser with the rules.
Well... I guess the scientists just take that on 'faith'.
Barack Obama claims he evolved on same sex marriage.
No more than there is that the continent of Antarctica existed 300 years ago.
