I understand the desire to see more alien creatures. I also know that scientists insist that the Human body plan is likely not the norm for aliens. But I disagree, just on the fact that if Extra Terrestrials are DNA based life, like Earth is, then that means similarity in form and function, among land creatures, certainly. And technology begins with fire. That means a body plan that can create and control it. Not just as primatives with torches, but everything that follows, from blowing glass to forging iron cannons. The Human Body Plan is very conservative, without all of these free-flowing tentacles and tails and things that would just get in the way. Humanoids make perfect sense to me.
