Alhamdulillah, it's good you are open minded, BUT Adam was created in Jannah, NOT on earth.
There is absolutely NO EVIDENCE to support that Adam was created on earth and was "sent" to Jannah. Don't come up with your own assumptions with no evidence, this is very dangerous.
Allah created Adam in Jannah, and when Allah gave life to him, he went to give salaams to the angels etc, then at a later period Iblees and other angels were commanded to bow to him.
"We said: 'O Adam! dwell thou and thy wife in the Garden; and eat of the bountiful things therein as (where and when) ye will; but approach not this tree, or ye run into harm and transgression.' (The Noble Quran, 2:35)".
It was AFTER Satan refused to bow and he tempted them to eat from the tree that they were expelled from Jannah:
"We said: 'Get ye down all from here: And if, as is sure, there comes to you Guidance from Me, whosoever follows My guidance, on them shall be no fear, nor shall they grieve. But those who reject Faith and belie our Signs, they shall be companions of the Fire; they shall abide therein.' (The Noble Quran, 2:38-39)"
Allah created Adam in Jannah, and from Adam's rib did Allah create Hawwa. It was the decree/plan of Allah all along for him to eat from the tree which resulted in him (Adam) from being expelled from Jannah.
Abu Hurairah narrated that Allah's Messenger said: "Adam and Moses argued with each other. Moses said to Adam: Your sin expelled you from Paradise. Adam said to him: 'You are Moses whom Allah selected as His messenger and as the one to whom He spoke directly. Yet you blame me for a thing which had already been written in my fate before my Creation?' Allah's Prophet Muhammad said twice: "So, Adam outclassed Moses."
Umar Ibn Al-Khattab also narrated that Prophet Muhammad said: "Moses said: 'My Lord! May I see Adam who removed us and himself from the Paradise?' So Allah made him see Adam, and he said to him: 'Are you Adam?' Adam said: 'Yes.' And he said: 'Were you the one in whom Allah breathed His spirit, and before whom He bowed His angels, and to whom He taught the names of all things?' Adam answered: 'Yes.' So Moses said: 'What made you remove us and yourself from Paradise?' Adam said unto him: 'Who are you?' He said: 'I am Moses.' Adam said: 'So you are Moses the prophet of the Children of Israel. Were you the one Allah spoke to directly?' Moses answered: 'Yes.' Adam said: 'Why do you blame me for a matter which Allah had predestined?"' So Allah's Prophet Muhammad said twice. "Adam outclassed Moses."
We are all descendants of Adam. And Adam was not created in an evolutionary process, he is a separate creation. Every single human on earth today and throughout history has descended from Adam, EXCEPT Jesus, he has no linage.
We do not descend from anyone but Adam.
