What a raging turd of a narcissist you are!
No matter... Andromeda is like 2.5 million light years away,
doing the quick Google. At the speed of light, we're talking
a 5 million year wait for a return signal.
Why? It's pointless.
I mean, a civilization is just so advanced it can fart
Dyson Spheres, but it's too stupid to figure out how long
it would have to wait for the neighboring galaxy to send a
reply? And how long does the average species even survive
for? Hmm?
SETI is full of shit. THAT is the issue here.
They've concocted asinine scenarios "to test" when failure
is virtually guaranteed.

Effectively, SETI is only capable of detecting two types of
signals, and they are...
#1.  A signal sent as an intentional effort to communicate with
us, or at least let us know where they are.
#2.  Communication to or from a space craft.
By far, and it's not even close here, the most likely signals
to reach us are communications to and/or from a space craft.
Space craft fly of to space, one presumes, and quite possibly
some distance from the home world... or solar system.
Anyway, unlike surface communications, communications with a
space ship would have to cross vast distances and maintain all
integrity.... EXACTLY the type of signal SETI would want to be
looking for.
But SETI, according to their own protocols, would dismiss such
a signal.
I mean, unless it's traveling line-of-sight towards earth, it
would be moving, and even the tiniest change in angel would
send it ridiculously far away from the original point of
detection. In other words:  It couldn't repeat.
The concept is simple enough:  Point a laser at the moon strong
enough to produce a visible dot. Now, whip that laser around.
The result is that dot moving across the surface of the moon
FASTER than the speed of light. You're just a mortal being, and
in your case not a very good one, but even your humble movements
of the laser, here on earth, produce incredible movement on
the surface of the moon...
That's a directed signal through space, a beam.
Thus, in the most likely instance of anyone sending a signal
capable of traversing mind-boggling distances of interstellar
or intergalactic space (communication with a craft), SETI is
incapable of "Confirming" a signal. They just can't. According
to their protocols, they don't exist.
You can check back at the same coordinates a thousand times
and you're just not supposed to see them again...
So we're left with these daft scenarios where aliens are
constructing intergalactic christmas tree lights, or "Hello,
my name is Oggarkich.1.23.Ndsch-blop" signs.
