Islam used to be the forefront of scientific and mathematical discovery.
No, Islamic COUNTRIES did. They didn’t achieve excellence in science because Islam benefitted science.
They achieved excellence in science compared to Christian countries in large part because their religious authority figures didn’t stand in the way anywhere near as much. Not because religion helped.
Believing in god have nothing to do with science
Not true. They are polar opposites. That’s why scientists are disproportionately atheist and agnostic: the evidence based mode of thinking employed in science doesn’t mix with the superstitious and unquestioningly convinced thinking of religion without some SERIOUS cognitive dissonance.
it’s that irrational thought that make us human
No. That’s not being human, that’s being brainwashed and/or obedient to authority.
You’re right that it’s irrational and that irrationality is an inherent part of being human, but the SPECIFIC irrationality of religion is learned and enforced, NOT inherent.
Yeah, rights are for people. Not entrenched power structures arranged within semi-arbitrary lines on a map.
