NASA scientists (and I use the term scientist loosely) are being paid to come up with scenarios such as one included in a report that
“…speculates that aliens, worried we might inflict the damage done to our own planet on others, might “seek to preemptively destroy our civilization in order to protect other civilizations from us.”
“Humanity may just now be entering the period in which its rapid civilizational expansion could be detected by an ETI because our expansion is changing the composition of Earth’s atmosphere (e.g. via greenhouse gas emissions), which therefore changes the spectral signature of Earth,” the study says.
“While it is difficult to estimate the likelihood of this scenario, it should at a minimum give us pause as we evaluate our expansive tendencies.”
And it could be that aliens will show up and offer to solve all of humankind’s problems, including curing cancer in order to fatten us up and transport us to their home planet in order to eat us… Oh wait, that’s been done….
But seriously, I’ve read enough sci-fi that I could come up with any numbers of alternate scenarios as laid out by the writers of the past, I don’t need to be a highly paid “scientist”……
