On the contrary, outgassing is the most likely cause because all present knowledge validates and supports the expanding earth theory. You simply choose to remain ignorant and ignore anything from anyone which doesn't fit your agenda. Then you toss on complete nonsense about laboratory analysis, and as if the very same people whom are critical to keeping a lid on truth will then provide truth? So somehow you conclude that it is completely logical to ask those involved in a crime for evidence of their innocence.
On top of that you're simply making stuff up, not to mention ignoring the links, and the combined in our face data we can see with our own eyes; chemtrails, oil leaks, gas leaks, sinkholes, melting ice fields, massive increases in geological activity, massive increases in bolides from space, and the hits keep coming.
If this were an isolated incident, if we didn't already have cases like those in California, then maybe I wouldn't be so hostile. However, gullibility is stupidity and it's the product of delusional thought and willful ignorance, and that's what you're showing me with your complete disregard for all the links and other information I provided and which I freely donated in time for your own well being.
Go hold hands with notdej for all I care
