Do you think intelligent life exists on other planets besides earth in the Universe

I personally think its a fact that lifes exists beyond earth, we as humans just can't find any other intelligent life right now cause of the vast distances in space and how long it would take for us to communicate with each other, even if these beings did some how pick up a message from us or we picked up a message from them. All the scientists seem convinced that life is beyond earth, they just don't have the evidence currently to prove it because they can't travel the vast distances of space and don't have the life span to verify it. but the odd's say life exist and intelligent life. there is thrillions of galaxies, more galaxies then grains of sand on earth and in each galaxy is billions and trillions of stars. so doesn't that in itself prove that intelligent life does exist somewhere out there. In this day and age to deny that life exists beyond earth is a very arrogant statement.
