It's called speculation. The aforementioned phrases show how it works.

Wow. Good catch.

I'll take my "science" with a bit more certainty please!

Nothing in any science is 100% certain. Every measurement contains some degree of error. Science, even quantitatively, can only be certain to within the limits of the errors in measurementor observation.

Well then, you will have no science at all. Science doesn't deal in certainty, merely in preponderance of evidence. Currently there's not much evidence out there regarding the origin of life, so this field is admittedly pretty speculative. It is relatively more speculative than many other areas of science, but no other area of science is certain. Any of the currently accepted ideas in science could be demonstrated to be incorrect at any time. Of course, it takes more than someone saying that they don't believe it to do this.
