If exoplanets discovered by scientists are what they were thousands of (light) years ago what if life developed on them thousands of years later in our present time? Theres no way to confirm the existence of alien life because you're always looking back thousands of years into the past with the telescopes!

>thousands of years

More like millions/billions
The most distant individual star visible to the unaided eye is a little over 4000 light years away

Well, actually observing the ariens isn't the only way of confirming their existence, we could also pick up on waves, if any ever come our way, which is super unlikely.
>>
Why don't we just call them over the radio?
>>
What makes you think that there could happen any significant change in evolution in that time?

I think that even if we cant send humans on those planets, we should send life. Just shoot some microbiological cocktail on few of those exoplanets. It doesn't matter that it wont evolve to be humans, life is life.

Ok then what about the sun it takes 8 minutes for the light to reach us does the sun not exist too?
>>
>>7842665
If the sun magically vanished it would take 8 mins for us to see it disappear from the sky
>>
>>7842670
8 seconds, not minutes. Gravitational waves cannot be faster than light.
>>
>>7842102
You'ee assuming the aliens are interested in wanting to be found/find other life out there. Why do scientists assume aliens would have human psychology?
>>
>what if
>>
>>7842670
Yes but that means the sun existed so op is an idiot
>>7842671
What?

>>7842671
Are you stupid

>>7844729
he stupid
>>
>millions of visible stars in night sky
>most are millions and billions of light away from each other and us
>all look exactly the same size
has someone come up with an explanation for this yet?
>>
>>7844999
You are retarded

See
>>7842101
All stars to the naked eye will be similar in appearance. Look at any Hubble image of deep space and you see incredible diversity.

a light year is a measure of distance you worthless cunt

>super unlikely.
Radio waves have been leaving Earth for decades now, at the speed of light. The possible number of aliens receiving them grows as the area of a sphere grows.
>>
>>7845071
But after a light year or so the signal is so degraded that its almost indecipherable
>>
>>7841895
We will soon have the instruments to analyse the atmosphere of exoplanets. One of the first things to look for is free oxygen since that does not occur abiotically. From what we know you need plant life or similar to photosynthesize oxides into free oxygen and other chemicals.

You asked about life but perhaps you had intelligent life in mind?
