When did Christianity invent hell and god’s imaginary condemnation of man?

When did Christianity invent hell and god’s imaginary condemnation of man?

I have read where god cursed the ground, Gen 3;17, cursed is the ground for thy sake. Nowhere do I see where god condemned or cursed mankind directly.

When and why did Christianity invent the notions and lies surrounding hell and man’s condemnation?

Was it to loosen our purse strings or just to use fear as a tool of social manipulation and control?

Why do the gullible still believe this obvious lie?
