There's nothing wrong with "report". Look at the other verb.
You can, and it's better that way.In the USA a lot of people claim to see [STRIKE]the[/STRIKE] UFOs.
Can I also say "In the USA a lot of people claim to have seen [STRIKE]the[/STRIKE] UFOs"? Can it be used for a regular activity or for something that has already been done?
In the USA a lot of people report of watching the UFOs.
In the USA a lot of people claim to see the UFOs.
Above are your sentence from post #1 and then your revised sentence. Is there a reason why you changed "report" to "claim", despite being told that there was nothing wrong with "report"? The change of verb requires changes to the rest of your sentence. Please see if you can fill in the blanks below:
In the USA, a lot of people report ____seeing__________ (single word) UFOs.
In the USA, a lot of people report _of seeing_______ _____ (two words) UFOs.
In the USA, a lot of people claim _to____ ____see____ (two words) UFOs.
In the USA, a lot of people claim to have seen____ ______ _______ (three words) UFOs.
You can, and it's better that way.
You shouldn't use the definite article because you're not talking about specific UFOs that you've mentioned before. People think they've seen UFOs in general.

Done
Okay, I can use the "have seen" version.
That's correct, but it uses three words where the exercise asked for two. The words you need there are "having seen", and I agree with emsr2d2 that this is beyond your current level.In the USA, a lot of people claim to have seen UFOs/a UFO.
