Many alien Civilizations existed in our galaxy.

According to the current study, alien civilizations have existed in our galaxy for millions of years.
According to NASA experts, the Milky Way may contain more civilizations.
Strangely, NASA started publishing extraterrestrial data. However, their most recent research came to the almost unquestionable conclusion that civilizations have existed in our galaxy for billions of years.
Researchers at the California Institute of Technology and NASA’s Jet Propulsion Laboratory collaborated on the study.
Aliens are organized into organizations throughout the galaxy.
The investigation’s findings suggest that this catastrophe occurred about 8 billion years after the formation of the Milky Way.
This demonstrates that several extraterrestrial civilizations existed in our galaxy in the past, all of which were destroyed or obliterated.
According to research published at arxiv.org, intelligent life in our galaxy, the Milky Way, should have appeared at least 8,000 years after its creation. Experts estimate that the catastrophe occurred about 13,000 light years from the center of the galaxy.
The researchers who reached this conclusion—Xiang Cai, Jonathan H. Jiang, Kristen A. Fahy, and Yuk L. Yung—used various statistical models to establish when sentient life should have first appeared in the cosmos.
Based on a number of features, including well-known astrophysical features of the Milky Way and unusual elements, including the process of abiogenesis, this conclusion was reached.
The process of generating life from non-living material is known as abiogenesis. This is believed to be the most likely explanation for the evolution of life.
When considering the likelihood of life in our galaxy, there are three things to remember.
Civilizations can be characterized by three main characteristics.
Thanks to mathematical theories that predict the existence of life on planets like the Earth and in stars like the Sun, life could begin through the Poisson Process or abiogenesis.
We also thought about how different evolutionary timescales and species extinctions might have an impact.
The findings indicate that self-annihilation is the most important factor in deciding how long an extraterrestrial civilization can last in our galaxy.
Furthermore, information about a location for intelligent alien life with complex life has been found in an annular region, about 8 billion light-years away, with the peak point shrinking geographically and temporally from the peak point. Therefore, there is a very high probability that intelligent life exists in the Milky Way’s inner disk.
The simulated age distributions clearly show that most conscious life is still in its infancy. Because of this, it is difficult to see or distinguish it.
Is it possible to be sure that our civilization is not the only one of its kind in the Milky Way? We may finally discover the truth about our ancestry and the feasibility of coexisting with other civilizations with the help of this investigation.
