Two sides to every story

I know that there is more intellagent life out there. We can't be the only ones humans were made because of a asteroid hitting Earth. Even if that hit that created us was a one-in-a-million chance doesn't mean it can't happen again. The universe is huge. Humans can't even wrap there mind around, some of us still don't know how big our galaxey is they just assume that is our solor system. My point is that there are probably billions of galaxeys and planets like ours so it we are one-in-a-million chances are there a more like us.
