I Don't Account for What I See...
...I haven't read the other responses to this post, but I did want to say that if there is evidence (indicators that can't be refuted) of these early life forms, then they must have existed. As to how long ago, well, that is a question I will have to wait for God to explain in eternity.
I do not feel like going through all the mental and intellectual gymnastics needed to argue, one way or the other, when it comes to the who, what, where, why and when of this factual evidence.
Like I have chosen to do with the Old Testament stories, I am willing to accept, by faith, what I see (and can't explain) because I know that all of this will be understood at the end. Sometimes I think the devil gets tons of mileage out of these unsettling findings, because he can use them to create riffs in the universe of understand, and often can keep some folks from coming to Jesus.
To argue that some form of evolution is impossible is meaningless, because if you just look at the realm of intellectual advancement in mankind, it is a form of evolution, and our technological growth is also a form of evolution. All things do evolve in one sense of the definition of the term; however, I will never accept the argument that we evolved from apes. If someone wants to believe they have a monkey for a great, great uncle, so-be-it. I can clearly see where the human body has benefited from growth (evolution) or the intellectual expansion of science and nutrition, but not to the point where one species evolved into another. To believe that would be to deny Scripture, and we must take our being here on faith, which at times is not simple, but it is pure!!! :type:
