You would possibly like it to be true for obvious reasons.
The likes of Hynek, Hoyle, and a few others like Arp for example, are/were professional men, unlike you river, or MR, or myself, but even as professionals, they have been shown all to be wrong in their assessments into their fields of Interest.
And there will of course be more isolated professionals that may not adhere to the general mainstream in the future, and guess what? They too and their claims, will be looked at by other professionals in their fields, [as opposed to the likes of you and MR] and some like Einstein did, will be accepted and lauded for whatever discoveries they find......others like Hoyle, and Hynek and Arp, will be discarded as nonsense.
Science is a discipline in progress river, and all current accepted theories were at one time simply hypotheticals....That does not then follow that all myths, hypotheticals pseudoscience and quackery will achieve the scientific theory status. The scientific method will sort those out, as it always has.
Let's hope that some extraordinary evidence or actual contact is forthcoming re ETL, before I kick the bucket!
At present though, there is zero extraordinary evidence.
