okay .. so iv been workin on a lot of researches abt alien existence and the claims tht the other planets or our moon in dis example, wudn have any life forms due to non existence of water .. but have u ever thot .. y do u alwaiz search for water .. agreed tht all livin beings require water for livin .. but has one imagined tht they r ET or aliens .. v dont have proof tht aliens too require water for survival .. their body cud b made up of somethin els .. scientists all over the wrld can in no way state tht since the moon doesn hav water or atmosphere, der is no life form .. or even mars .. though they r searchin for water as proofs of water deposition in earliest yrs has been found .. de claim ders no life formm .. i feel one cannot claim to knw alien structure witout a sample, which is not existed till date. wat do u think
