If all these "scientists" go to their scientific community and seek endorsement from their scientific bros and sisters, we will not be speculating here. Instead many of these "scientists" prefer to go to cyberspace or publish books hoping to get support from generally gullible laypeople. We cannot term them true scientists in that sense.
Since leaving school, almost 50 years ago, I have not touch science.
When these "scientiest" put their findings on cyberspace or publish books it is not their sole aim to get support from gullible lay people. It is a public service to share their findings with lay people. We public are lay people when comes to science but we are certainly not gullible. We are grateful they share their effort with the public and join them in their research journey and hopefully one day the truth will surface, just like the discovery of dinosaurs, it took a bone and now we get a picture of the dinosaur era. I was also in the same position then, what you term "gullible lay people".
I too have left school 45 years ago and I am grateful to all these "scientist", historian, archeologist, Egyptololgist, Astrologist, etc. for sharing their research effort with the public. It is a journey these people are taking. They never claim they are right or wrong. They are just voicing their opinion.
I think you left school 50 years ago, closed your mind and think that you know everything already.
My friend we are already in the information age and I am very glad that now I can get these informations, true or false, at my finger tips.
I may no longer be young but I certainly still have a open mind to process the informations available which will certainly make us less ignorant old people.
