Do aliens look anything like us?

What would aliens look like if we ever discovered and observed them? Will they look anything like us humans? Without any scientifically verified examples to analyze we are left with making educated guesses and some creative speculation to work with. In this video we will discuss what we can know about aliens without ever making contact with them.
* Apologies for the poor audio and video qualities! First video and absolute minimal hardware. Pretty much a test approach, but I promise to improve as more videos are released. Thanks for your patience everyone.
Please help grow and support this channel by subscribing to it and liking the videos! I very much appreciate it and I promise to continue to help nourish your curiosity by exploring more big questions in the future.
Thank you
