Fireballs appeared in Yushu, and powder clouds appeared in Delingha. Are the aliens here?

Fireballs appeared in Yushu, and powder clouds appeared in Delingha. It was not aliens who came to earth. The National Space Weather Monitoring and Early Warning Center said that this situation is likely to be a fireball formed by extraterrestrial objects entering the atmosphere.

One: The only anomalies in the sky are the unknown red light in the sky of Delingha, Qinghai, which has been madly spread on the Internet recently, and the UFO in Xiangda Town, the immigrant area of Nangqian County, Yushu, Qinghai. Unknown red light appeared in the sky of Delingha, like a pink cloud-like object. This pink cloud-like object appears over Baishushan and the urban area for about 35-40 minutes. The UFO in Yushu did not appear as long as the unidentified object in Delingha. Only appeared for a short time. When it appeared, the dark night sky around it was as bright as day, accompanied by harsh noise. Many netizens linked these two unknown events, thinking that aliens had made a trip to the earth and returned to them with pink clouds. However, according to the documents issued by the National Space Weather Monitoring and Early Warning Center, this event is only a relatively large-scale asteroid impact event in recent years. It is said that this is just a fireball that rushes into the earth's atmosphere from outer space, then decomposes by heat, then scatters debris, is irradiated by the sun, and finally forms the remnants of the fireball, and there will be scenes seen by netizens, like aliens entering the earth and dissipating outside the earth like clouds.

Two: Humans habitually attribute UFOs to aliens. People always like to attribute things that are difficult to explain scientifically on earth, or UFOs, to aliens. But so far, humans have never known whether aliens really exist. Many people claim to have seen flying saucers and aliens, but after investigation, the scientific basis can be verified. Scientists have also put forward various possible conjectures about the existence of aliens, but this still does not explain whether aliens really exist, but it does not affect human imagination.
