Reb eliezer,
What I’m saying is that Adam Harishon ate from the עץ הדעת on the sixth day but Hashem let him stay in גן עדן over Shabbos which is why He put the angels by the עץ החיים because if he was kicked out of גן עדן right away why does anything need to be put by the עץ החיים?
I hope I’m being clear
