One of the reasons people are skeptical of alien encounters is the huge technological barriers for space travel. The distances and time it would take to travel to Earth from another planet capable of sustaining life is insurmountable to some. If it is possible, it's highly likely an alien race would be insanely technologically advanced. Given this technological advancement, is it even possible for us to interact with them in any meaningful way?
For example, try interacting with an ant on a cultural level. We might say an ant has some level of intelligence but not nearly enough for it to understand anything we try to communicate to it nor communicate to us. This might be analogous to our potential relationship with alien life. We could be ants to them in terms of intelligence so maybe they are visiting us constantly but we have no way of knowing just like the ant might not see us observing them.
