I said this in another topic, but while I think it would be shortsighted to say that "aliens don't exist" period, I don't believe we've "made contact". If aliens were able to reach us, then they'd be so technologically advanced that they'd really have no reason to do so in secrecy. Either we'd have something they need/ want and they'd just come and take it, or we'd be so insignificant to them that they could just come by and snuff us out just because.
I also don't really buy that all the governing bodies of the world could all work together to keep contact a secret from the general public. Someone would spill the beans, or some country would want the bragging rights of being the first to make contact. It would just be such big news that there's no way it could stay contained. And again, given that it would be blatantly obvious to any observing extraterrestrials that we'd be completely defenseless against beings far more technologically advanced to us, I don't see why they'd operate in secrecy or anything like that.
I generally imagine that "UFOs" are either fringe experimental devices, or advanced spy drones, or things like that. Stuff with more logical explanations.
