Why does Creationism has to be wrong?

Think of it that way, science means to 'observe'...observe the stuff around you, and think of how they were made...the desk or the bed wasn't made by its own neither it was just there..how do we know that? we know that by previous knowledge..so therefore we come to a conclusion after you make your hypothesis and yze your observations that there must have been someone who created the desk and out all the pieces together, and cut the wood the right size, etc. so now think about people. Evolution can always been proven wrong, but you will never be able to find evidence to prove Creationism wrong.
