Infinite number of planets with life

If you don't proceed from what we know, then you might as make up any shit you want.

sorry man, I'm just saying that what we know (or we think we know) can change as it changed in the past, and there is a lot of questions that can not be answered yet... I'm not saying its wrong or false, is one probability but is certain not sure..

When we know something in a scientific sense, there is a lot of good evidence to back it up. Things that we "knew" in the past that have been since changed weren't based on scientific reasoning, and are therefore meaningless. For example, we know that the Earth orbits the sun, and we know that because of a more advanced understanding the cosmos. We're not going to determine in the future that this is incorrect because the fact of the matter is, the Earth does orbit the sun. We know this.

Science adjusts its views based on new evidence from observation.
