Do you believe UFO?

I believe in aliens, I think that since there's life on our planet, it's very likely that there may be life on another planet as well. However, that doesn't mean I believe in UFOs. If there is another living being on another planet, it doesn't mean they can travel across the universe. It's possible, but it's also possible that they can't, or couldn't or whatever. Plus, the universe is absolutely gigantic, so they may not have reached this side yet.

haha,it's such a funny topic.. Fact i dont believe,but once i use some time to think about this,if UFO is a real thing,that's too horrible~~Does it will take one or two of us out of the earth?I can not image that~~
