There aren't "lies being passed off as facts" That is what you're ignorant about. I can tell you that Dawkins and Tyson do not "believe" in alien seeding theory. They are simply pointing out how implausible theistic explanations for the universe are while showing their open mindedness. Trust me, I'm very open minded to explanations about things. I'm very skeptical of claims made by people - which is what The Bible is if you should choose to believe it. 

The universe as we observe it did have a beginning. I agree with you. But claiming the second law of thermodynamics for some reason as to why life can't come from non life is foolish. Have you looked outside today and noticed that bright thing in the sky? It's the source of all the energy on earth. The universe truly is decaying and in an unfathomable amount of time every atom will be ripped apart. What that means from some "before and after" story about what the cosmos is I have no idea. Being cautious and open-minded are important.
