If you take an hour as a representation of all human history, then monotheism only came in the last 20 seconds of that hour and even less so for Islam.
From Hasan Radwan's very eloquent video...
"Is Monotheism (Tawhid) the default natural (Fitrah) belief of mankind?"

The overwhelming majority of human history has consisted of animistic and pagan beliefs - https://en.m.wikipedia.org/wiki/Timeline_of_religion - not monotheism and certainly not Islam, which arose in, if not post 7th century Arabia. There's no evidence for Islam pre-existing 7th century Arabia or many of the 100,000+ prophets, Muslims like to fantasise about - https://old.reddit.com/r/exmuslim/comments/4ucfob/islam_is_a_copy_of_the_sabians/d5otmpm/
This is a complete opposite history of what you'd expect if 'Fitrah' actually existed, it doesn't, hence our long pagan history.
