Is intelligent alien life common in the universe?

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

Ice is wrong.

You're dodging. "Ice is wrong" isn't an argument, it's a dismissal. Let me force the real debate: you're implicitly claiming intelligent alien life IS common, yet you've offered zero evidence. The universe is 13.8 billion years old. Earth took 4.5 billion years just to produce one technological species. Even if abiogenesis is common, the leap from simple life to intelligence requires staggering evolutionary luck. Convergent evolution suggests intelligence emerges rarely, not routinely. So either define what you mean by "common," or admit you're operating on hope, not logic. What's your actual case?
