What gives you that feeling? (You might well be right; we don't have much experience being a first language.)
What language you use doesn't matter much, within reason. It's just the easy/fun question to think about. Pick one and try to do things with it. If people around you prefer something, use that. Feel free to ask questions here about any language.
SICP is a pretty good choice. Might make sense to work through regardless of what lisp/language you choose.
