Earth exists for 13.7 billion years, and human mind has started to mature in civilized way,
from just 5000 years.The level of technology used by present human civilization cannot
detect existence of aliens around the galaxy.Technology designed are just to catch the signals,
only when aliens wish to contact, (say something like WOW!).
If taken a look at one of Saturn’s satellite, possibility of alien’s existence can be expected,
but it is covered by ice cage.Now, technology and investment/interest is not in that manner
so that humans can explore it.
One thing interesting here is,even if aliens existed with capable of traveling up to here but,
expecting that “historic movement in (specifically for)human history(only)” to happen only
at this particular span of time of 5000 years , that too,only when humans have evolved to
keep track of history of happenings around them! then, the possibilities becomes even mere
than expected.
Even if they had traveled before 5000 yrs, or will be traveling after 5000 yrs,chance of them
landing on this planet, just because it is earth! The chance of aliens not willing to come in
contact with humans is as possible as chance of earth staying stable for so many years for
supportive for existence of intelligence!
Talking about science and technology, moving further in future and thinking about time traveling
becoming possible, How much worth or interestingly can your era exist for a society of future.
40 yrs 2 world wars , 100 yrs of boxer war.Just less than 30% of planet being democrat that too
for just 62 years, even after coming to know about democracy for some 5000 years!
Your own people don’t like to make a stop and a have look at you( if they are
civilized).
Strange planet ,where,
“Worms always been worms for chickens and, Chickens always been
chickens for humans.Wish had at-least if, Ever Humans been humans for humans. Or Is
that what they are the way they had been !!?”
Again, Your region and your time being now is so valuable at-least for present level.
30% demo-graph is democratic for almost 6.2 decades ! WOW W!!! yes it is !
especially for people believing in Humanity and self respect of certain kind!
Probably , according this period of time, it’s only us around the the near by galaxy, that might go on to build a great and strong base for future in terms of advanced CIVILIZATION OF HUMANITY that might help to see increase in span of time supportive for research and development of advanced technology to build Your Imagination of Spaceship.
