Why would I? I don't necessarily believe it occurred.
The most obvious and logical conclusion is that the microbes are from earth! Why would any scientific person think otherwise without one single shred of evidence? hmmm?
I have no idea. I am person involved in science, and I don't have enough data to make any iron clad assertion, one way or the other.
Could it be that they start with a BELIEF that God doesn't exist? Yep. All beliefs flow from one's belief about God.
Another assumption on your part.
Give me your evidence...and please spare me your non-scientific speculations based on presupppositional assumptions.
Your problem is quite a simple one, really. You are assuming that those who do not necessarily agree with your idea and/or explanation of certain phenomena or theories must therefore subscribe to another, in this case, microbes originating in outer space. You are quite wrong in making this assumption.
I want only the facts and real evidence. If you can't provide it, then maybe you should examine your own beliefs and how you came to hold them.
Oh, I'm well aware of what I believe and how I came to this point, but what I believe is not the question here, it's what beliefs you are foolishly trying to ascribe to me.
First you start with the BELIEF that there is no God, then you try to make everything fit that belief.
Not I, Chicken Little, not I.
Then tell me what your beliefs are. It is obvious from your answers and tone that you do not believe that God created life. If I am wrong, then please tell me what your beliefs are so that I can be more specific, or admit I was wrong. When I deal with atheists and agnostics, I like to question their beliefs - they hate that becuase they rarely have a good defense for agnosticism or atheism.
