If you mean Adam of whom we all decend from?
In the stories of Islam they believe in Adam and Eve and the what happened in the Garden except for the fact of original sin, so in a way the believe in the Pandora's box story, where Pandora opens the box of evil and all evil spills out to the world.
so it would be assuming that yes Adam is a Muslim.
No, Neither Adam nor any prophet founded Islam. Allah (God in English) is the founder of Islam. Refer to question below.
Islam was not discovered. It was the first religion sent to Adam.

Historically, the prophet of Islam was Prophet Muhammad. But in Koran it is said that Adam was a Muslim too. So, either Adam or Muhammad.

yes
Islam does teach that Adam ate of the tree, but Islam does not teach that sin is hereditary.

Adam (peace upon him)
A: Islam was started when the first prophet, who was the first man on Earth i.e. Adam was created. Every prophet preached some portions of Islam. For example: the Kaaba was built by Adam, the slavery in Islam was initiated by Abraham, etc., but Islam was completed by Muhammad(PBUH).
