Are there infinite Universes

Hello, Thank you for accepting this debate. 

           My argument goes like this if there were infinite universes were everything that can exist does exist, then there would be a universe were there is universe traveler, in fact there are infinite universes were there is a universe traveler. So in one of these universes there must be a traveler that wants to talk to me specifically in this universe at this time. However that isn't happening. Another example would be in some universe there would be a machine that can destroy every universe, and with the infinite universes there would be a universe that has this machine and intends to use it right now. But that isn't happening therefore there cant be infinite universes were everything that can exist does exist.

           If there were infinite universes were just the laws changed but its not necessarily everything that could exist does exist then there would be a universe were the laws make universe travel super easy and we are brought back to my first paragraph.

         If it is just parallel universes were every decision made creates a new universe then there would be decisions made by great scientists that would progress humanity way farther to a point were they can travel universes and we get back to my first paragraph.

 If it is just infinite universes were it is the exact same as this universe and everything happens the exact same then eventually we would invent universe travel in the far future and when we travel to another universe how can that universe copy what we did and go to its own universe?

My first argument still stands
