Aliens Are Silent Because They Are Extinct
In research aiming to understand how life might develop, the scientists realised new life would commonly die out due to runaway heating or cooling on their fledgling planets.
“The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens,” said Dr Aditya Chopra from the ANU Research School of Earth Sciences and lead author on the paper, which is published in Astrobiology.
“Early life is fragile, so we believe it rarely evolves quickly enough to survive.”

About four billion years ago Earth, Venus and Mars may have all been habitable. However, a billion years or so after formation, Venus turned into a hothouse and Mars froze into an icebox.
Early microbial life on Venus and Mars, if there was any, failed to stabilise the rapidly changing environment, said co-author Associate Professor Charley Lineweaver from the ANU Planetary Science Institute.
“Life on Earth probably played a leading role in stabilising the planet’s climate,” he said.
Dr Chopra said their theory solved a puzzle.
“The mystery of why we haven’t yet found signs of aliens may have less to do with the likelihood of the origin of life or intelligence and have more to do with the rarity of the rapid emergence of biological regulation of feedback cycles on planetary surfaces,” he said.
Wet, rocky planets, with the ingredients and energy sources required for life seem to be ubiquitous, however, as physicist Enrico Fermi pointed out in 1950, no signs of surviving extra-terrestrial life have been found.
A plausible solution to Fermi’s paradox, say the researchers, is near universal early extinction, which they have named the Gaian Bottleneck.
“One intriguing prediction of the Gaian Bottleneck model is that the vast majority of fossils in the universe will be from extinct microbial life, not from multicellular species such as dinosaurs or humanoids that take billions of years to evolve,” said Associate Professor Lineweaver.

Complete and utter nonsense. There are at least 60 known alien humanoid races known to the US military. So where are they? We should stop looking where we are currently. Our solar system is the least likely place for life to start – as it is now.
It is considered that our local star was previously a dim Red Giant and we were probably enclosed in its plasma atmosphere. Hence our energy source was far more consistent: nutrients, moisture and useful em radiation were available 24 hours a day, every day of the year. Life grew luxuriantly because we did not have the extremes of hot and cold that we now suffer. It may have been dimmer and a more red/blue light but that was sufficient for our needs. Ancient man recorded “the purple dawn”. That is why we are more sensitive to green light as it was in shorter supply then. Gravity would have been considerably lower too – hence prehistoric creatures grew to greater size.
Hence you will notice that the typical ‘alien’ (grey) has eye covers which allow it to deal with the low light conditions. That’s how the earliest sample of image intensifier lens was found on the Roswell crew in 1947. The CIA Stargate project sent its operators on Remote Viewing missions to alien planets and it was always noticed how dark they were. The beings mostly living below ground too.
That’s what I have found by reading the evidence, and seeing a real, piloted UFO in 1964.
