A bunch of uncritically informed assumptions here Venus.
"With the measure you use, you will be measured". You cannot quote Biblical sayings as if they are actual truth!
They represent the precepts and injunctions of leaders of the christ cults from the time of writing and this one is clearly false. Kind and generous people are just as likely to be struck by lightning or a bus as any criminal is.
You talk of heaven as if we all come from there, you might for all I know! except my experience tells me that there is not one ounce of evidence that anyone ever had any pre-existence nor any after life, as much as these popular rumours have for millennia pervaded religious minds. Evidence is required.
Flowers, flower scent and coloured fruits function as attractants to insects, birds and animals for the sake of perpetuation of their own life forms. The species which fail to attract or reproduce simply die out. It could hardly be said they were created for humans because flowering plants evolved during the time of the dinosaurs and all plant families had appeared before hominins did in the Late Pleistocene (i.e. geologically recently). The Rose family for example including herbaceous plants, apples, pears, plums etc developed in the Eocene Period (following the dinosaur extinction) which began 56 million years ago ending 33.9 million years ago.
It is anthropocentric to imagine they were created for our pleasure.
