Sheer conjecture is more accurate than theory and/or testing? While both theory and testing are only as good as their latest incarnations, they are part of the scientific process of reaching conslusions. Conjecture is only a starting point.

RE: "And based on the engineering experiments and simulations the WTC should not have fallen down... "

Says who? They survived the impact as expected. They did not survive the fire caused by the fuel from nearly fully loaded fuel tanks. It is ridiculous to claim theories are useless by using a misleading application of a theory to an example it was not designed to handle.

RE: "By your reasoning the 16 million year old bacteria found in the Allen Hills Meteorite should have been alive as well. Well was it?"

Two big glaring holes in the point you are trying to make. There is no consensus the fossil life claims are correct. More importantly though NO ONE has ever claimed the bacteria were living when they left Mars. No rational person would ever claim fossils ejected from Mars would suddenly become living upon arrival on Earth.

RE: "Last I heard even the Surveyor 1 bacteria was found to be from lab contamination on Earth, not left on the Moon as originally argued..."

And you point was? Bacterial contamination does not prove bacteria could not survive those conditions. This could be tested in laboratory or on the ISS, but I'm not sure it has. My understanding is that contamination is considered a high possibility but not beyond a doubt. The problem is either explanation is based on Earthly bacteria so you can't use genteic tetsing to rule out either possibility.

RE: "Again science requires proof, not speculation. Next thing you know you will be claiming that someone is making Dinosaurs from the DNA they recovered...."

Funny you should say that. What proof do you have that Martian life will be hazardous? Or are you admitting that your worries have nothing to do with science? Do you always use such double standards in your arguments? I'll leave the fictional scifi nightmare scenarios to people like you.

Funny how familiar your self contradictory reasoning seems.
