Yeah, lot of Jews are confused over the idea in Ecclesiastes 12:5-7 about one's 'spirit' going back to God Who gave it, when one dies in their flesh, with their flesh going back to the earth where it came from.
They don't want to admit that "spirit" is about one's spirit with soul being the actual 'person' that returns back to God. Instead they want to push that it's just an animating force in nature in general.
Eccl 12:5-7
5 Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets:
6 Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.
7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
KJV
The false belief that our spirit with soul is part of our flesh body, an old JEWISH FALSE TRADITION, if true would mean the 'person', the individual', NO LONGER EXISTS at flesh death. It would mean YOU ARE GONE, NO MORE, WIPED CLEAN as if you never existed! That is the what the ATHEISTS believe! They believe when we die we are NO MORE, like we never existed.
How then, did Lord Jesus go to the "spirits in prison", and preach The Gospel to the dead, so they could be judged according to men in the flesh, but live according to God in the spirit? (see 1 Peter 3 and 1 Peter 4).
