The little seedling does look very much like a baby oak tree of some kind. If it is not where you want a tree, try transplanting it. Just make sure you dig deep so you do not cut off the taproot and get a good ball of soil with it.
I have seen this before but off the top of my head I am not sure what it is. It does look like a red oak plant but still I wouldn't be 100% sure. I guess you could look at some of the other plants were you are at and see if you could find a match. But I would look on the web and look at some plants on there you might be able to have more luck there.
