The critical question is:Is life the only type of material complexity expected in other habitable zones, or is life only one example of many types of complexity? In other words, is or is not life an inevitable consequence of the evolution of matter? Given the proper conditions and enough time, is life a sure bet or is it quite rare?
The notion of time travel is rooted in the early 20th century physics of Albert Einstein. In the 1880s, two American scientists, Albert Michelson and Edward Morley set out to measure how the speed of light was affected by Earth’s motion through space. They discovered, to their amazement, that the speed of Earth made no difference to the passage of light through space (which they called the ether). No matter how fast you travel, the speed of light remained the same.
There are many temporal anamolies scattered through over the world that are enough to prove that our assumed history is wrong. I find them as strong evidences against our perceived view of evolution.The Paleozoic Era is a major division of geological time, preceded by Precambrian time and followed by the Mesozoic era, and including the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. The Paleozoic Era began about 570 million years ago and ended about 240 million years ago.
When considering the presence of life under adversity, we shouldn’t be too quick to rule out environments based solely on extreme properties. The underwater hydrothermal vents are very hostile places as judged by life on or near Earth’s surface, yet life manages to thrive around them under conditions quite unlike anything at the surface. Undersea volcanic activity spills forth scalding-hot water rich in sulfur and poor in oxygen that manages to feed “extremeophilic” life by a process known as chemosynthesis—an analog of photosynthesis, yet one that operates in total darkness.
This is not to say that intelligence could not arise from plants or fungi– just that the development period for such would seem to be far longer than that already postulated for sealife in general, and so intelligence of too high a plant or fungi content would virtually always lose the survival competition on a given world to more robust and mobile animal forms, under most imaginable conditions.
