Thanks Nick for your useful comment - one of two people who replied to the post who do not have need to see a psychiatrist. Thank you for your non predjuced comments.

Before you people others attack people on an opinion they do NOT have find out what they believe. You go wa****ing about fact - get your own correct.

AND before you people imply in your little minds that I :
1) believe in aliens (I do NOT - amazing really since most of you do),
2) that aliens ever lived on mars or anywhere else (I do not - but many of you do)
3) that plants and animals ever existed on Mars (I do not - I actually believe everything is geology but am willing to look at the data with an open mind and discuss the alternatives to find out unlike most of you who just want to prove your beliefs are correct - belief does not equal fact GARY - go get an education)
4) That I believe water flows on Mars like on earth - I never said that and do not believe it, I just said it was not all CO2 - and am not the one saying that Mars geology is like earth, that Mars was a wet planet once, or that everything on Mars is different..... just to be different - I suggest you read your own posts.

BUT thanks your your opinions - your scientific replies show your capacity to think logically.
