To me, I think the first thing was realizing what bubbles are. Yes, very basic, but as a preschooler, I didn't realize that they were just air inside water. After that, I think it was the realization that when you rotated say a pencil or a marker, the end that is further from the point that you rotate it covers a greater distance than the points that are closer to where you rotate it, and it does so in the same time, so it moves faster. In maths, the earliest thing I can remember was when I observed that the difference of the squares of two successive natural numbers is the sum of these numbers, followed by the observation that the difference of the squares of any two natural numbers is actually the sum of the numbers multiplied by their difference. I didn't know algebra back then, so I didn't prove it, but when we eventually learned the identity a^2-b^2=(a+b)(a-b), it all came back to me, and I have to say it felt pretty good!
