Yes imho; a USSR experiment conducted on Mars showed methane was produced. A sign of biological life, nasa also conducted the same H20 experiment & again confirmed the production of methane. However they decided to relay the results as possibly contaminated. You might like to look into the blue-berries on mars, which have been shown to migrate & duplicate themselves as well has send out filaments. The reason why usa keeps covering up the information about advanced knowledge is that they believe having paid for a think-tank back in the 60's (from memory) that it would shake the foundations of society & a collapse would take place. This is why UFO's & many anomalies we are now 'allowed' to know about. Are covered up, from upper-atmospheric lightening aka (also known as) sprites. Which can be red & blue that originally were kept top-secret. Because the government & scientists didn't know what they are, so they use plausible deniability. What they now like to do is present the wider world with the knowledge they were discovered or documented decades ago & that you've been late to the party. Which when you have pilots & military fighter pilots & astronauts/cosmonauts reporting these things & other interesting guided large objects that they are the time were off little value & were made to discount their assumptions. Take the example of two crop-circle, note the chilbolton one's are in an area inside a security exclusion zone. Two very different glyhs & the knowledgeable amongst the readers will not a resemblance too the arecibo.
