The deduction of the studies done by David Icke show that big possibilities exist to exist. We're multidimensional creatures
that age contemporaneily in
different frequences and dimensions. The mind of a person coul be synchronized over lots of
wavelenghts of consciences and comprehension, different between them. This is the reason that we met, in human generation, lots of different ways of perception, conscience and prospectives. It's probably that another civilizations with different ways of life and of perception, situated on another wavelenghts that our senses aren't able to identify. We can look a planet in tv noticiary and notice only types of earths, rocks, apparently empty and without life, but the real truth is that it's only the unique thing that our senses are capable to notice, because we look to that planet behind our space-time reality, not corresponding with the temporal reality of that planet. In another dimesions, we could be that same planet that we see desert, this full of life, as much as ours. It works more or less like the radio or tv stations that transmit, dividing the same busy space of our body, but in different frequencies.
