I'd never thought about the smell before. When evil starts up, that incense stuff coming out of shops selling tarot cards and special magic amethyst for instance, the wafting is pretty revolting. Amethyst is still an attractive mineral but something's been overlaid to make it ugly.
Death did not exist before Eve existed, therefore no insect could prefer the aroma of corpses and be attracted to stinking flowers, to pollenate them. Here are some demon-possessed flowers.
God made MODEST apparel from leather Genesis 3:21 definitely NOT minimalistic loincloths but full-sized garments. Did a random impala or giraffe get slaughtered for the purpose? Once sin blasted everything, creatures would start dropping dead very quickly if their new reduced lifespans were compared to how long they'd otherwise exist for as a percentage. I doubt that God skinned a ruminant alive and left it there squirming – but anyway, after The Fall there would be carrion and a stench would have descended on Eden all the way from decomposing mice to rotting mastodons.
At the present rate, life expectancies will soon reach zero and God can incinerate everything. Those still living will be burned alive.
II Peter 3:5-7 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: whereby the world that then was, being overflowed with water, perished: but the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
