Did Prophet Adam (peace be upon him) descend in India, and what was the first tree God created?

The authenticity of Adam's descent, peace be upon him, in India and Eve's near Mecca has not been established; it might be from the Israʼiliyyat (Judeo-Christian traditions). As for the first tree Allah Almighty created, there is no definitive knowledge about it. However, exegetes mentioned that the olive tree was the first tree to grow on Earth and after the Deluge. The questioner is advised to focus on what benefits him in his religious and worldly affairs, and to ask about matters that entail a ruling or an action.
