Fact: each succeeding generation has had erroneous assumptions about the origins of the universe and of life in general.
Fact: Reality has as a constituent called continuity. (Certain forms of continuity can be induced only by rational means, though some lend themselves quite well to empiricism.)
Continuity states that once a relation has been established as fact, even though we have no empirical evidence that the relation may continue, it is most probable that the relation does indeed continue. This is because all known qualified examples of continuity do continue. Therefore, once a relation is established as valid, and since we have
no other examples of where continuity does not continue, it is therefore very probable that the established relation
must continue.
Fact: All former generations have had erroneous assumptions about the origins of the universe.
Premise: Therefore we (almost assuredly) have erroneous assumptions.
The probability of this statement being true is quite high.
We may indeed have a better and more truthful understanding of the universe than they did, but the light of knowledge does not suddenly blaze forth with the magnitude of a supernova. It usually comes gradually over time. I will venture that in a couple of hundred years, people will look back at us and say the same things we say about people who believed the earth was flat.
I also find it amusing that some so-called 'intellectuals' can take such a biased stance as to gloat over the idiocy of a small faction of people who oppose their points of view, while at the same time not be humble enough to admit that there exists a comparable amount of idiocy within their own camp.
