Have you ever wondered if miracles really did happen...?

back when Jesus or Mohammed was around? I mean what if there was a drought and some guy just happened to have said "It's going to rain.." and later that day some thunderstorms ped by?You think they mistook evens said in the bible as miracles...maybe they were just normal things..liek the thing with the fish..maybe the fishes they swam uphill not down hill so there wasn't much catch..stuff like that..
