That would be cool. It would also be funny if you just hovered there and let their arrows bounce off until they got tired of shooting them. Then just start flashing a bunch of colored lights in geometric patterns. Once you have done that, leave the immediate area for a bit.
Then come back at night, abduct one of their tribesmen and put him in a bright room. Once he is in the room, we come in with dark sunglasses with big lenses and snazzy white coveralls to go with the shades. We should ignore him/her if they try to speak to us (we likely won't understand their language anyways). At this point we should shove probes up their asses and then take blood and other bodily fluid samples. If the abductee is female, she should be impregnated (artificial insemination is best, but if you are desperate just find a human with similar skin color and don't have him where the coveralls and glasses combo).
In the event that you do get a female and impregnate her, come back in 3 or 4 months (time isn't important, just be sure to get there before the end of the second trimester so that the baby has very little chance of surviving outside of the womb). When you come back, put the coveralls and glasses back on and abduct the woman again. Once you have her, remove the fetus and have your dark skinned pal make some hand gestures to indicate that the baby would live "up there" (point up to the sky etc). Then place a tiny piece of a meteorite under her skin (I recommend administering a good narcotic dose here, not enough to put her to sleep but enough to make her groggy and unaware). You can either keep the fetus or throw it away at this point, you won't need it again for our purposes (though I recommend keeping it as you can sell it to stem cell researchers or you can dissect it yourself if you like embryology and you just never no when an aborted fetus might come in handy - it's best to store them in a deep freeze or similar device).
Finally, every few years, come back and abduct her again. Each time you do it come back with the same weird looking kid (note that he must be both wierd looking in some fashion and of similar skin color and body type to the abductee). Have her play with the kid and give her food and drink that would appear strange to her (you could just bring something from burger king just make sure to present it in an odd fashion). If she seems upset to leave the kid behind, have the kid indicate that he can't survive outside in the air (he could just take deep breaths and then pretend to gag while pointing outside).
This is a wonderful hobby, but be warned that it's easy to get carried away with it.
