why do scientists always say that religion clouds there views of evolution, creation and so on?

Im not a religious person or a scientific person Im a layman. but in my opinion, there are experiences that i have had, others have had and people of science cant explain said experiences. they have a theory, but no real proof.
so i just dont get how scientists just dismiss something that doesnt have 110% proof behind it, even if they seen it happen with there own eyes.

to me it doesnt really matter, life is great and things change, but ive always wondered why scientsts just hate on religion, whats the reasoning behind that?
