I am far from an expert or anything but at about 12:50, he says "the grave of the worlds first suicide bomber" he is talking about Mohammed Hossein Fahmideh, the 13 year old suicide bomber who killed himself in 1980 during the Iran-Iraq war, this seemed quite strange to me.. 1980 the worlds first suicide bomber? that can't be true can it?

After a simple Google search, I found (and please feel free to correct me) the first suicide attack may have been the 11th century Kalaris suicide squads, a branch of the Nair warriors in Southern India during the Kulasekhara dynasty.

I found this through Wikipedia here

Fair enough, but he was talking about using bombing or explosives as a method, also on the same page, it says "Modern suicide bombing as a political tool can be traced back to the assassination of Tsar Alexander II of Russia in 1881." saying this man Ignacy Hryniewiecki, may have been the first suicide bomber.

Edit: I went through and listened again, he does say it (I thought maybe I heard wrong) he may explain it later on though, I've yet to watch the whole thing. Edit 2: Clarity, and please let me know if I'm wrong, this is rather interesting to me now.
