As I mentioned, if something has good substance to it, it does become accepted later on.....people, especially in authority postions used to believe in these:
The Earth is Flat
Man can not fly
Man will never go to the moon
And those sure as hell changed in time. I feel this shall as well, regarding alien life. Only those with something to lose will panic.
As to the Earth being flat, only landlubbers ever thought that. Seafarers throughout history knew otherwise.
Man cannot fly.
I never heard of anyone saying man will never go to the Moon.
