You make absolutely no sense at all. You're hopeless with this weird
combination of attack and blame the other guy first illogically bad
grammar, repetitious posting trolling and obsessed.
And wrong to boot. I'm not sure you could be more perfect for
You have spent this thread ignoring or dodging questions. I have answered every question you have put towards me, while you have not!
Like the above, you say all this stuff, but never back up or give reasons for why you are writing said post. Why have you done that through the entire thread?
I am still waiting for answers to questions I put go you, which you ignore because you simply do not have the answer. But you have done this yo not just me, but go other people who oppose your fairytales.
You only get brave when someone else attacks me, then you spring into life saying this and that about me, without posting any proof!

We should all get along.
It is good news that we are not a random accident. The obvious necessity of an Intelligent Faculty involved in the spawn of the universe and its precise laws indicates that there is a higher purpose to our lives. We have this same Intelligence within us, use it for harmony, not for strife. We have more in common than we do differences.

How do you know this "intelligent faculty" is our friend? And what higher purpose do you speak of?
This is a list of exoplanets. As of 8 December 2019, there are 4,104 confirmed exoplanets. The majority of these planets were discovered by the Kepler space telescope. In addition to the confirmed exoplanets, there are 2,420 potential exoplanets from its first mission that are yet to be confirmed, and 892 from its "Second Light" mission. Additionally, a growing number of planets are being discovered by the Transiting Exoplanet Survey Satellite (TESS).
For yearly lists on physical, orbital and other properties, as well as on discovery circumstances and other aspects, see § Specific exoplanet lists
We have used a more or less empirical statistical approach to evaluate the probability of the existence of extraterrestrial life as a function of its stage of evolution. The results permit determination of the order of magnitude of the distance separating these forms of life from the Earth. Depending on this distance, we discussed the potential of detectable biosignatures. Finally, we have shown that the more extraterrestrial life has evolved, the greater its likely distance from the Earth, and thus the lower the possibility of its detection. Consequently, if extraterrestrial civilisations are possible, we could only detect them at present if they are able to communicate in space using a radio or a light signal. Similarly, even if the probability of microbial life in other stellar systems is relatively high, we could only detect it on habitable planets if it has reached a sufficient stage of evolution to release gases that modify the atmosphere of the planet. Finally, even if we are now able to make in situ investigations on several potentially inhabited bodies of the Solar System, these investigations are still limited to surface exploration. The only current target on which we can search for extra-terrestrial life is thus Mars.
Despite these apparently discouraging conclusions for the possibility to detect extraterrestrial life, this study also demonstrates that life is probably common in the Universe. Moreover, even if the probability to detect extraterrestrial intelligence is close to zero, the probability to detect photosynthetic life on exoplanets is not at all negligible. The probability to find active microbial life on a body other than Earth in the Solar System is also high enough to justify future projects involving investigation of the icy moons of Saturn and Jupiter, as well as the present and future missions to Mars. The approach outlined herein has been used to simply and successfully explain the challenge of astrobiology to the general public, in particular during a two day training course for teachers, and appeared to be very useful and well-understood.
