You should be careful in anyone claiming to be working for "US Military Space Program" "atheist turned creationist" if they do not make their credentials very easily available. Usually a curriculum vitae would help, but just merely finding this:
Spike Psarris was previously an engineer in the United States’ military space program. He entered that program as an atheist and an evolutionist. He left it as a creationist and a Christian.Source
This site is dedicated to exposing the bankruptcy of the evolutionary model, especially in astronomy.
makes it suspect. Consider this comparison.http://www.internationalcommunion.org/index.php
Now, you as an astute Orthodox Christian will ask, what is the credentials of this organization in calling itself an Orthodox Church? Who is the bishop of this Church? Who's the patriarch?
Another comparison is also this organization that calls itself "Shine International", started by Atef Meshreky turned OCA monk. For sometime, they had the bio available of this man (who's now called Fr. Macarius). He's no longer there (maybe OCA is deciding to be a little stricter with him?). Nevertheless, this organization is very clear it's made up of many denominations and there is a removal any direct or indirect association with the OCA, at least publicly, so as not to give false credentials.
Same thing with Spike Psarris. As someone who is very much involved in the science world and academia. What are his publications? What are his references who can vouch for his work in the military space program (a very vague phrase)? What type of work did he do in the program that makes him qualified to speak about creationism and astronomy?
You know, I can say, "Hi, I'm a doctor." But the government also has to sanction my practice, and if I'm not a licensed practitioner (which is readily available online), my MD or DO is not enough.
Given my previous research of organizations like the Creation Institute or Discovery Institute, it has been associated with a lot of lies and deceptions that frankly, I can't really trust this source without proper credentials. How do I know he was an atheist turned believer? What's his life story? What references or witnesses do you have that can vouch for your story? Psarris doesn't seem to have much of that. If I can't convince programs and hospitals to hire me based on two or three sentences, then you as an informed and intelligent human being should also be on your guard for someone who does not like to make his credentials so clearly available, especially when he wants to sell you something or be an official voice of publication and views.
