We are using tin cans with strings. Aliens are really on a different frequency.
Some of this exploration is extremely jumping the gun.
We are barely in the kindergarten stage of space exploration, and hundreds of years away from actually exploring the stars beyond our own system - which leaves five times that hundreds of years in decades, before such information will have an ounce of practicality to human space exploration - leaving amble time for such endeavors in the future.
Meanwhile the practical limits of our current kindergarten stage of actual exploration are starved for funds so much that priorities on those funds limit what we can do to less than what we know we can do.
We should waste less funds on the not-yet-practical and shift all NASA funding to what we can practically do now, and practically do sooner; not what we won’t need to know for hundreds of years.
Puny Earthlings!
Send your box cameras into space!
What you will see is our invasion fleet getting closer and closer!
Soon, you will know the wrath of the Glaxnovian Fleet as we conquer you and free our brothers, the squirrels!
