Most of you possibly are the most interested in finding live forms similar to us. 

But there are much more interesting creatures too. My favorite live on Sun, actually inside one.

They have got excellent conditions to grow. Plenty of energy and unlimited resources.

Due to high temperature their frequency is quite incompatible with ours. And don't look for arms and legs. They don't need any.

By definition creature need intelligence and need to participate in exchanging information. Some of stars that we look at are completely rebuild from inside, some spectacular behavior is actually sign of live. Supernova explosion could be just act of will activity with purpose.

Black hole could be also full of live. Or stream of light. Maybe even space itself

Most likely human evolution also lead to change of the form. But I think to some extend the space creature may sometimes look jealousy at us with our plain body and prosaic problems, imagination.
