To develop intelligence, such that the humankind has, is a time-consuming process in nature. It may need billions of years. What would an intelligent kind do if they would want to discover other intelligent kinds, and do not want to or unable to create it? What if they just want to discover how nature produces it? Because producing intelligent life by nature is a time-consuming process, even if the discoverer has a long lifespan, it is still not an effective way to wait billions of years at a place where it may happen, not to mention the risk of the disturbance by being present.

If the discoverer has the technology to travel fast, a working method could be that the discoverer visits the promising places from time to time but travels between them with speed close to the light. This way the discoverer - according to the relativity theory - spends little of its own time but still can see the slow-developing process of a promising, intelligent life. The discoverer could even make some effects on this process during the occasional visits. This would be an effective method to discover, see, and maybe intervene in the development of intelligence, and at an adequate time, make contact.

Can we see these visits and this kind of effect in our history? Because the intelligent kind's goal is primarily to observe, and it can just wait for the adequate time to make contact, these visits and maybe the influences are certainly hardly recognizable. And we may only have conjectures. Sure, we have conjectures!

What does it mean that we have not been contacted yet? We can see in our case, that after a technological civilization developed, the speed of the development accelerated exponentially. What this means is that if an intelligent kind reaches the technology level, they could also reach the capability to travel close to light speed in a quicker time, compared to the time needed for the intelligence to develop in natural ways. Therefore, if we are not the first intelligence that reached the technology level, if there are others, it is very likely that they already reached the adequate technology level to discover the universe. If we are not alone, it is very likely that they already discovered us, only we are not ready to be contacted yet. Are we close to that? Or will we go extinct before that? Or would they intervene to prevent that? Are we valuable enough to be contacted sometime?

These are many questions without answers. At the very least, we can watch for quickly moving objects. Maybe one of these objects is them.

And the last question: Will we ever be the discoverers?
