LOL Well, I haven't seen the show yet, but I just hope we are all still around this is proved one way or another. My own theory is that, since most things must start from below the single-cell level (there was even an entire stage of evolution that started, faltered and died out, Enchelons or something), we might be in for a bit of a surprise on how similar life on other planets may be in many ways, but then, I'm not a Xenobiologist or the like, it's more a gut feeling. I've never denied the possibility I could be wrong

Still, the whole point of theories is for future generations to grab them and stretch them to breaking point and we won't know till we go take a look
