It's my belief that meat eating came into the world after man's fall in the Garden of Eden where God had imposed a vegan diet. Genesis 1:29-31.
Coming from someone who views the universe through a mythological lense, this doesn't surprise me. You presume I view your religious texts as documented history. You might as well have told me that Demeter, the Greek Goddess of the Bountiful Harvest imposed a vegan diet.
Nope. I think they were for nuts and for those tough, uncooked veggies.
Actually your molars would be better for nuts as the fulcrum force required by your jaw to crack a nut is not sufficient for frontal teeth. Try cracking a walnut with your canines. Our sharp ancestral cuspids/canines are for tearing through the flesh of mammals and fish. Leaves and grasses do not require daggers for cutting teeth. Do some googleing and you'll see that species that do eat only grasses and leaves do not have canines. Heck, most don't even have upper front teeth as they mash up the tough vegetable fibrils with flat teeth. They also have specially evolved digestive systems for digesting plant cellulose. We don't.
No diseases are contracted when engaging in the sexually moral relationship between one man and one woman approved by God as stated in the Bible.
This implies that diseases are only transmissible by intercourse which is untrue. And sexual diseases can be prevented and cured without the need for any moral codes. Vaccines and antiviral therapies will continuously emerge to treat and thwart these.
May be those engaged in sexual immorality will be encouraged to stop and think about the hazards of their behavior and cease such activities in the interests of preventing death and suffering.
Yes people should be encouraged to educate themselves of the risks of contact with other organisms (in any form) but our biological urges prove too strong for most. Humans are a communal species with aggressive sexual tendencies, even those awash in mysticism. Biology is too strong a force, even for opiates like religion.
Will these antibiotics prevent the diseases from developing in the first place or are they only "after the fact" cures?
Both. Surely you've heard of vaccines.
I've read somewhere that these antibiotics are pretty strong medicine and have harmful side effects.
Some have side effects due to our lack of knowledge and technology as to how to design more precise treatments. This will change in the coming decades and centuries. Very few diseases will plague technologically advanced civilization soon as the tools to micromanage biological function are emerging now.
