Have I proven our universe is not infinite

IMHO Awaiting debunk

IT is probable to me that if our universe is infinite than everything that could possibly exist has to exist because of the infinite amount of probabilities

So I will send out a radio signal in a straight line through the infinite universe. My signal would say.

"I John. Ask you to come and say hello and show me where you come from"

If the universe is indeed infinite the infinite probability that I’m looking for is

"The radio signal will be picked up by an advanced civilization that have mastered time and space travel and will then come back to me to say hello and show me where they came from"

The fact that they have not come back to say hello means that the universe cannot be infinite with an infinite amount of probability

You're thinking of an infinite NUMBER of Universes. A Multi-verse theory. Just because our one Universe is infinite in time and space doesn't mean that their are infinite pobabilities. Though, maybe there would be if we were around long enough.. Anyways, no you didn't disprove the Multi-verse theory. According to that, there is an infinite number of universes, an infinite number of realities, yea it could and should at some point happen. But your not in that Universe so you will never know if it did or not.

Radio signals and frequencies loose their intensity after a while. Some of the radio frequencies SETI has sent to our nearest star Proxima Centauri are still getting there. Plus, even if there are advanced civilizations that have "mastered time and space travel", then don't you think they would have discovered a more advanced and more technelogical form of communication than radio? If so, they may not even recognize it. We will never know if the universe is finite or infinite.

IT is probable to me that if our universe is infinite than everything that could possibly exist has to exist because of the infinite amount of probabilities -- False. You have NO understanding whatsoever of probabilities and statistics.
