One day, we're going to encounter sapient life that isn't our own. One day, we're going to encounter people that aren't like us. One day, we will make contact with beings who evolved somewhere other than on Earth. If I ever live to see that fateful day, I will stop calling -blam!- Sapiens "human". Being human and being a -blam!- Sapien are two very different things. Just because you're a -blam!- Sapien, doesn't make you human. The word "human" in my mind describes someone utterly selfless, someone who uses his sapience for the highest and noblest cause possible. He who attains altruistism becomes human. There are over seven billion -blam!- Sapiens living on this planet Earth but not every one of them is "human". Being a -blam!- Sapien is easy; you just have exist to be one, but being human? That's something else entirely. Humanity is a state of being. So back to what I said earlier, I'm sure we're going to meet other sapient species and when we first make contact with them, I'm sure more than a few humans will already be among their number. So ask yourself. What does it mean, to you, to be... human?
