Certainly not. The Iliad dates from 8th century B.C. , or perhaps a little earlier, and was not written down much before the 5th, while the Epic of Gilgamesh is at least a thousand years older, from around 2,000 B.C. Exact dates for the Mahabharata are problematical, but the oldest parts are ancient indeed, and easily as old as the Iliad
No, the Iliad is a Greek epic that was written before Jesus was born on earth, and many of the other events of the Bible.

The Odyssey is more popular than the Iliad. The Odyssey was probably written by Homer in his later years, thus was more refined than his earlier work. Moreover, the Iliad deals with battles and war, a harsher subject. The Odyssey, in comparison, deals with a fantastical adventure with monsters and gods.
The STAR of Iliad is Achilles
For most of European history the Iliad and The Odyssey were the earliest known poems. This meant that almost all later European poetry made use of the Iliad or the Odyssey in one way or another. During the twentieth century some poems earlier than the Iliad or the Odyssey were reclaimed:- particularly the Epic of Gilgamish. But the Iliad and the Odyssey passed for the earliest European poems for many hundred years, so they were the poems that everyone turned to.
