Describe UFOs . Do they really exist or is there any proof about their existence??? |
|
Answer» Just think we have developed our technology using too much of earths resources but science considers this technology nothing in comparison to future technologies. So the aliens who are much more intelligent than us in terms of tech that they can travel vsat universe in no time how much they would have used up their planet resource. So it may have ended in their planet. When they will see the veauty of our earth, its resources they may develop a greed for themselves and they are already advanced than us so it will be very easy for them just lke picking pencil to destroy human race and acquire resources. So i consider them very dangerous but 30 percent i consider them useful also because if we survived then we may learn a lot from them Well , i like to know the reason behind mysteries and ya tell me why u consider them dangerous. ?????? And ufo is also a united food organisation and it exists But tell me r u really intrested in getting explanations about such mysterious things??? And uf yes then do not venture alone to search like a scientist let them do their work as according to me it may cost your lufe even UF O are the undefined flying objects in air. Which is often considered as an extra terrestial object (according to humans). The existance of ufo are still a mystery. Some people says that they have seen ufo on earth , there are certain cases where people( the whole community) have seen ufo but the govt always says that they are only their jets or normal planes. However there are certain cases where people exclaimed to have met aliens and aliens have done some experiments on their body. Some even founded with strange radioactive things in their body but our friend science always gives a proper explaination about it and always oroves it to be a coincedence. For me ufo really exist and coming of them to earth may be very dangerous if you want to know why i consider them a dangerous i will tell you |
