I'm not "quibbling about a word." I just wanted to clarify the meaning of scientific theory because a lot of people misinterpret it to mean "evolution is only speculation and does not have enough evidence supporting it to be considered proven yet."

I'm aware that our very observation is all open to interpretation, and even what we consider solid fact may not be, but the way you worded it made it sound like you think there's not enough substantial evidence supporting it, or that there's equal scientific evidence supporting it and Creationism.
