"Believe :
To believe is to give his assent to a proposition which is held to be true without having the objective certainty of its truth. This is an opinion.
"When assent is sufficient only from the subjective point of view, and is insufficient from the objective point of view, it is called belief." Kant
Know :
To know is to give his assent to a proposition by having the objective certainty of its truth. This certainty is linked to validation procedures that can be justified.
Knowledge is knowing why one knows (justification in principle shareable, therefore universal claim). "
So I KNOW evolution is true.
Podarcis siculus is an example.
Looks to me you have a problem with "validation procedure" in science. Let me explain some things :
Dreams are not evidence.
Wishful thinking is not evidence.
Logical fallacies are not evidence.
Personal revelation is not evidence.
Illogical conclusions are not evidence.
Disproved statements are not evidence.
Unsubstantiated claims are not evidence.
Hallucinations/delusions are not evidence.
Information that is ambiguous is not evidence.
The Universe doesn't care what you believe in.
Data that requires a certain belief is not evidence.
Information that cannot be verified is not evidence.
Information that cannot be falsified is not evidence.
Experiments with inconclusive results are not evidence.
Information that is only knowable by a privileged few is not evidence.
Experiments that are not and cannot be duplicated by others are not evidence.
The wonderful thing about science is that it doesn't ask for your faith, only your eyes.
