Now how can that be? Mars and earth were all formed from the same material according to the BBT.
With all due respect, you need to be a rocket scientist to participate fully in this discussion. Our planetary probes have shown that every planet has a unique "signature" of various isotopes in specific percentages. That's the STRONG EVIDENCE that the ALH meteorite came from Mars. This new hypothesis, that the meteroite came from a specific location on Mars, is simply that...a hypothesis that needs more evidence. BTW, the BBT does not state that all planets are made of exactly the same stuff. It is obvious that there were mechanisms at work that differentiated the composition of each celestial body. Furthermore, current generally accepted theory is that the universe is many billions of years older than the Solar System. With the Scientific Method, the best system ever devised to determine Truth, hypotheses and theories are accepted or rejected based on objective proof and data. Belief has nothing to do with it.
I really wonder why they fear revelation of facts so strongly...
Maybe I should really light a fire and mention the epitome of sinful words: "evolution"...</SARCASM>
Some folks around here need a much bigger God...
This identifying the possible origin of the chunk of rock is mere taxonomy with an eye toward evolutionary theory. Taxonomy as a precursor of science is about on the scientific level of naming the animals. But, Newtonian mechanics does allow for interchange of small amounts of material between planets, which doesn't go far toward verifying bosonic string theory.
