Probability of Alien Life, UFO's and Alien microbial or multicellular life forms

According to current scientific knowledge, there are approximately 10^11 stars in the observable universe, meaning there could be over one hundred billion trillion stars out there, that's way more than the 100 billion sent to the Ukraine, about $900 per American! This number is constantly changing as new stars form and existing ones die off. Additionally, there are countless brown dwarfs, red dwarf stars, neutron stars, black holes, and other exotic celestial bodies floating around in space.

So, if we consider all these types of cosmic objects together, we might say there are billions upon billions of individual "sun-like" stars scattered throughout the vast expanse of interstellar space.

Despite extensive efforts by governments and private organizations around the world to investigate and understand these mysterious occurrences, no conclusive evidence of extraterrestrial origin has ever been presented to the public. Many scientists remain skeptical of such claims and attribute them to psychological or physical factors affecting perception or interpretation of natural phenomena. 

As we know many scientists are known to say and publish findings and scientific data to appease their benefactors, manipulating date to please those with the money has become a common problem in the scientific community.

Determining the exact probability of finding extraterrestrial life among the billions upon billions of star systems in the universe is challenging because it involves multiple variables and assumptions about conditions necessary for life to arise and thrive. Some researchers estimate the likelihood based on statistical analysis of known parameters like planetary habitability zones and the prevalence of certain chemical elements essential for organisms. Other experts use more speculative approaches grounded in theoretical frameworks or philosophical perspectives.

Overall, the possibility of discovering intelligent extraterrestrials seems relatively low given the immense distances involved and the rarity of Earth-like planets possessing stable environments conducive to complex biology. Nevertheless, the sheer scale of the cosmos means even tiny odds translate to millions or billions of potential abodes for living things spread across light years of space and time. Thus, despite long odds against success, human curiosity drives continued exploration and investigation of this fascinating question at the forefront of astrobiology and astronomy.

The probability of finding extraterrestrial life among the billions upon billions of star systems in the universe is difficult to determine due to various factors such as the lack of direct observations and limited data from current telescopes and probes. However, estimates suggest that the Milky Way alone may contain tens of thousands of potentially habitable planets orbiting stars similar to our Sun. Given the enormous number of galaxies in the observable universe, it appears likely that many other places hosting microbial or multicellular life forms could exist elsewhere in the cosmos. Yet, without concrete evidence or further advancements in detection technologies, the true chances of encountering extraterrestrial civilizations remain uncertain.
