Is it true that we are Missing Intelligent Life Because We’re Looking Into The Past?

Researchers around the globe say that they have discovered new planets thousands, millions or billions of light years from Earth. Doesn’t that imply that the pictures those researcher get are thousands or millions or billions of light years old? On the off chance that clever life framed in one of those planets, and on the off chance that they are additionally hunting down new planets, then doesn’t it imply that those life structures will see just a rough planet not livable to life? 
The quest for planets outside our close planetary system has been extending pretty quickly as of late with the information returning from the Kepler mission, however no one has figured out how to distinguish a planet entirely as far away as a billion light years from Earth. Kepler can just identify Earth-like planets that are less far off than 3000 light years from our close planetary system, in an exceptionally contract locale of our world. 

Our world is around 50,000 light years from focus to edge (so around 100,000 light years over), and the following closest vast cosmic system is Andromeda, sitting around more than two million light years from us. While our present perceptions of the Milky Way persuade that there’s a planet around basically every star in our cosmic system, we haven’t possessed the capacity to review that quite our very own bit universe, not to mention the stars in Andromeda, which would be exponentially more hard to watch. The farthest strong recognition of an exoplanet is still just around 21,000 light years away. 
Be that as it may, you’re completely right – our pictures of exoplanets are generally as obsolete as they are far off from us, and we won’t ever have the capacity to get around that constraint unless we can go going to them so that the light-postpone isn’t so serious. A planet that we see at 10,000 light years inaccessible from us will be a picture that has gone for a long time. 
On a topographical timescale, 10,000 years is only a blip of time – the Earth was basically fit as a fiddle as it is presently, however we people had rolled out less improvements to its surface. On a human timescale, 10,000 years has had a major effect. 10,000 years returns us to the Neolithic time – the end of the Stone Age, around the time when earthenware was creating, and we were starting to develop plants for agribusiness. So a savvy human advancement, 10,000 light years far off, that is a little while ago searching for other life in the Universe would see our Earth as a rough planet with an environment, sufficiently far from our sun that water could exist in our climate, and in the event that they figured out how to look at our air, they would see that it is generally nitrogen, with some oxygen and carbon dioxide in it too, and that it contains water vapor. They would not have the capacity to tell that there are animals on that planet that are 10,000 years from building up the web, neurosurgery, and machines ready to recognize minor bends in space itself. 
This sort of time postponement is one reason that researchers get additional energized when they locate an adjacent rough planet that may have the capacity to have fluid water on its surface – if the planet is near us, then the time deferral isn’t as terrible as a more far off planet. (It is likewise much less demanding to watch these adjacent planets in any level of subtle element – the further away you are from the Earth, the harder these estimations get.) We just figured out how to identify the substance of the air of a marginally greater than-Earth planet interestingly a couple of days prior — shockingly that planet is absolutely without water, having a climate of generally hydrogen and helium, with some hydrogen cyanide tossed in for additional harmful flavor. This planet is just 60 light years away, so our picture of it is just outdated to the extent 1976—this specific planet won’t have developed into a friendlier, life-facilitating planet in such a brief span. 
Be that as it may, suppose a super-smart progress out there has assembled a unimaginably substantial telescope, and has the force (and the time) to recognize planets circling stars in a far off world, and they pointed it at our Earth. In the event that they happened to be 2.5 billion light years far off, our planet’s air would be amidst an emotional change. 2.5 billion years prior, our planet was amidst the Oxygen Catastrophe – the most punctual photosynthetic microbes were dumping oxygen into the climate speedier than it could be consumed, and oxygen was gradually developing. As oxygen was a dangerous repercussion to the single-celled life which had been living in a delightfully without oxygen environment, they would need to adjust or cease to exist. Perceptions of our planet from that separation would be capable just to tell the spectator that our planet existed, it has water in its environment, and how quickly we go around our star, however not even an insight to our space-investigating future.
