This is actually not true! Islam brought the current 0-9 numbers to Europe then to the rest of the Western world. They had a lot of astrologists, mathematicians etc. A very old culture. I lived among arabs for almost 3 years when I was a kid and I can assure everybody: they are just as good as every other nation all around the world. They are fucked up by KM who got their lands turn to deserts so after thriving they were downgraded to third world countries before oil was found. Then they became a target again
And beware! KM want you to turn on Islam so WWIII can be triggered!. Don't fall for it!

I know they were very smart ppl and Mosques were like Univercities but now it`s all about control and that long lost Islam has gone
