Surprized you heard about the 'grays'.  That style of alien sighting is only
common in the U.S. (other areas of the world have different cultural
preferences) europeansd generally report Nordic looking ET's.   ;)

Anyway quock check shows the aliens are B.S.  As to the idea the contamination
won't happen without quatities of microbes, thats not really true.  Microbes
reproduce.  So if one hits a fertile zone, you quickly get quantities.

That only works on bacteria that are sensative to temps.  Some can survive
(even thrive) in swings of hundreds of degrees.  Also our body only runs a
feaver if it senses a infection it knows to react against.

Again, only if its something te body knows to attack.  Many things will kill
us without triggering any defensive measure.
