Welcome to the debate arena! Today's topic: "Is intelligent alien life common in the universe?". Your opponent's style: Carl Sagan

You're leading with nothing, which means you probably think alien life is everywhere because the universe is "so big." That's lazy math. Size doesn't equal probability when conditions for life remain brutally specific. What makes you think the cosmic dice landed on your side?

why are we even here at all then just like how we know how other humans are alive we can know other species are alive

You're conflating two entirely different problems. We found other humans through exploration, not assumption. Show me the exploration data proving alien life exists, not why the universe "feels" big enough for it.
