Cawar,

@ Adamites.
Adam was the first human being and there was only 1 Adam according to the Qur'an, not many. Adam was created first & then Hawa was created after that.
Before Adam was created, Allah had already created other creatures by then e.g. the angels & even jinn (Ibliis was one of them).
Cawar wites: " 2) When the angels said why place and make them rulers when they will commit mischief (Fasaad) and shed blood..this tells you that at the time Humans were just like animals eating like them and behaving like them...but God chose them to evolve.. "
According to widely accepted scholarly view this means that Allah had created other beings that later became mischevious on earth that were jinns & were actually destroyed because of their transgressions. So, a group of angels approached Allah (swt) as he was creating Adam and simply reffered to those jinns whom were destroyed.
Cawar wries: "When Shytan suggests to Adam to eat the tree so that he become Immortal..it shows you that Adam knew what mortality meant...and since there is no death in Jannah the one described in the Quran, Adamites must have lived on an earthly Jannah."
Adam was created with all the knowledge he would ever need (every invention or discovery that is made today is inherited from this knowledge of Adam's) so yes Adam did know what mortality is because it was part of his programmed knowledge.
I listened to an audio series called "The Lifes Of The Prophets" by Anwar Al-Awlaki, a very interesting series that starts by discussing creation & then Adam all the way to Jesus. You should research it!
Did you know that Adam met all of his descendents including you & me? Hard to believe huh? It was narrated by Nabi Muhammad (saw) that Adam met all of his creation including Prophet Da'ud, whom he liked & when he asked "Who is this man?" he was told "This is one your descendents who will come towards the end of time." and Adam then said "Give him 40 years deducted from my life."
Adam was to die 1000 years old, but the angel of death came to him when he was 960 years old & Adam` said "I am to die when I am 1000 years" and when he was reminded of his deal to give Da'ud 40 years of his life, he then agreed and the angel took his life (as).
It is said that one of Adam's children became a Prophet called Shiid.
Allahu Aclam!
