I don't know about some of them, but I will comment on the ones I do know about...
2. Actually the Sumerians are thought to have invented writing; it'd be wrong to call them Iraqi's. Just as Germany, the nation itself, didn't exist before 1860. Even if you'd like to do that, there's some debate and many think it was the Egyptians.
4. This is an invention of the The Holy Islamic Empire, aka The Ottoman Empire. Definitely not Iraq.
9. Most scientists say we descend from internal Africa... no one has ever said Iraq. Ur is also an ancient city of Mesopotamia, not exactly Iraq.
10. The Indians (not to be confused with Native Americans) beat them to the punch.
11. Um... so did every single other ancient civilization.
12. This is extremely debateable... some say Mesopotamians (Iraqs if you will), others say the Greeks, and yet others support the view of nomadic herdsmen of Inner Asia (Genghis Khan and Co.). Did I mention they all have strong evidence?
18. Uh... actually Canaan or the region that can be roughly called Palestine is the birthplace of Prophet Ibrahim (aka Abraham), PBUH. And what exactly is the "father" of Islam...
22. This must have been a long time ago...
24. I don't even know what this means... "the Germans of Arabs"? I guess I have to be European to get this.
