Caesar was assassinated and stabbed several times by several Senators and kept on ending his sentences with "for I am Caesar." Alexander was a king who made love with young Persian boys and his Greek officers and even publicly proclaimed his horniness by having coins minted with his likeness but with horns. Also, he probably wanted to make love to Darius II, and he probably did.
Its Darius III not Darius II.
More reasons why Alexander was great:
Alexander made many new cities.

He cleverly named all of them Alexandria. Except for one city which he named after his horse, Bucephales.
He was king of Macedon

and Pharoh of Egypt

at the same time.
His corpse was put on display in Egypt. The Roman emperor Caligula stole his armor though.
We can't find his body anymore.
Alexander led the charge in battle.

Yet survived. Impressive don't you think?
Alexander conqured the Persian Superpower and the entire known world by age 32.

Then he got PWNED by microorgaisms.
Alexander made a barbarian his Queen.
Alexander as a kid tamed Bucephales

when no adult could.
Alexander undid the Gordian knot.

A very hard knot to undo. He may have cheated though.
Alexander's middle name was "the" and his last name was "Great"
His statues were in their original painted form look kinda gay.

A discovery which inspired the movement to end "don't ask don't tell."
He conqured Iraq.

Something that the U.S has been unable to do.
He was Greek. Greeks are cool.
His father was the god Zeus. Achilles was his ancestor.

He noted that his step father Philip II wanted to make it from Greece to Persia

but couldn't make it from one couch to the next.
His favorite book was the war
