Odds of getting rabies notthrough?

is rabies airborne, like can it be spread throw people coughing and sneezing. also can you get it if you touch something and then touch your eye or rub your nose or pick your ear? like let's say you moe a lawn, can the saliva be carried throw the grass and then you touch the grass and then rub your eye or ear or face. i'm basically asking how long would the saliva last on the ground before the virus is dried up and not able to give you the virus. and is it possible to catch it throw plants and tree's (nature). i always wash my hands because i don't want to get sick from anything.
