Methinks the probability of life on planets is tied to the feasible distance between two optimal planets. Ergo, the lower the probability of life's occurrence on a planet, the greater the distance more likely between the constant planet (Earth) and the variable planet (the probability incarnate). With the uncovering of more planets and star systems in the observable universe that most likely do not contain life, let alone intelligent life (which would further decrease the probability due to the existence of only one (arbitrarily) species defined as intelligent currently known against the billions of species that do not meet the arbitrary standard, thus the probability shrinks even further), vastly increasing the likely distance between the constant and variable planets. Then, we have to account for the probability that the civilization initiating contact would be of such a greater intelligence as to reach a standard similar to that of a Type I, II, or III Civilization on the Kardashev Scale* (decreasing the probability of the existence of a species reaching a level similar to that of the bullshit III Civilization, but also increasing the probability that contact could be easily initiated from farther distances, throwing the entire system on a dynamic teeter-totter), so that the intelligent species would be able to reach us from such a far distance away. Ergo, the probabilities lie in favor with no, on this question. However, because of the very nature of probabilities, there is still, undoubtedly astronomically microscopic, a chance that two planets will contain life within mere light years of each other, and even smaller for intelligent life, thus increasing the probability for the initiation of contact due to the shorter distance and fluctuating other factors.
I feel insane for typing that all out.
I'll look at the provided videos when I have time to see what to make of them.
*Which is mostly arbitrary bullshit, but worth investigating.
