If pokemon were real..then there would be streets named after pokemon. The Chinese would probably eat some pokemon (since they eat dogs and cats and make people watch). There probably would not be airplanes, we'd use flying pokemon and there'd be rentals. Instead of war with weapons, war with pokemon (like the lucario movie), antidotes would be made from spinarak's venom and other pokemon, a tragedy would occur in which Grimar are released into the ocean and is polluting it. Too many humans with nasty habits out there. There wouldn't be terrorists. Pokemon would be used as weapons to many people, so there'd be no weapons, however, someone may threaten with a voltorb. Schools would teach more about pokemon than anything, including brand new subjects such as Pokemon Breeding, Training, coordinating, etc. There'd be no animals (obviously) due to the pokemon wiping out the animal population. This all sounds miserable, in a way, but the world would not come to an end. It would be rather peaceful, due to palkia and dialga, keeping the universe together. It's been awhile since I've seen that movie but if I remember correctly, they are one of few pokemon that keep control and balance of the universe. The only religions would be that of the legendary pokemon that some would worship. There are many other things that would change but it would be a hella long list.
