It took me a while to realize my younger peers have no recollection of times when we didn't know if the planets existed outside our solar system at all. Now it's like the obvious part in the Drake equation, mind-boggling.
...but damn if it wasn't bloody obvious there must be some.
(Perhaps theirs was the more scientific position, and I was just a nerd biased by science fiction stories. But then, I was taught the Sun was just another star, and if God wanted our solar system to be special, surely He wouldn't need to create more planets than just the Earth? I guess I had some intuition for Occam's razor before I knew it by name...)
I only got a more complete picture of the timeline of discoveries much later in life, from this video[1].
(EDIT: it seems that the first discovery was in 1992, when I was single-digit years old, so the noise I remember about Wolszczan must have been about the other discovery in 2007.)

On the other hand, when seeing a model of atom and solar system for the first time I was convinced reality is a set of layers with the micro- and macrocosm being just the two closest ones we're able to perceive, but I'm far less sure of it now.
Yeah, I thought like this too until we started covering the basics of quantum physics and our teacher explained to us how the Bohr model of an atom was only a crude approximation of what's happening. I no longer see atoms as miniature solar systems, but every now and then, I ponder if the planets aren't macroscopic electron clouds...
