so for a long time I've had an interest in both the paranormal and space, especially astrobiology, what's actually real and known possibilities.

that being said there's a huge unknown since we've really only found partial evidence for ET's on titan, that being some kinda microbe using processes beyond us to consume in methane, ethane, and other natural gasses and expel hydrogen.

so yeah let's keep this on topic, if you want to discuss UFO's and the like, keep it to known science etc, or setup a separate thread for the more paranormal side of things.

that being said, the possibilities of UFO's and such and likely technologies is fine, just as long as it doesn't drift too far off topic, being possibilities and what we know of so far.


now that all this is out of the way here's the facts as I understand them.

Life can probably form with more than just carbon based neuclaic acids with carbon being one of the easiest building blocks.

for life you need a molecule than can form complex structures, and some sort of solvent to help shape/disrupt it.

for water based solubility you have Carbon, Silicon, Sulfer, Boranes, arsenic, phosphorus, and metalic composites.

for solvents you also have ammonia, methane, hydrocarbons, Hydrogen sulfate and hydrogen fluoride.

there's more but these are some of the more common elements based on what we know and understand from studying life on earth.

for example, there are fungi and algae that are arsenic based.

early in earth's history life forms existed that expelled oxygen and consumed Carbon di-oxide and methane which made up the atmosphere of early earth, these were the first life forms.

you can also use acids and things in place of more typical solvents.

so yeah you can even make life using battery acid of all things... provided you have the right complex molecules to bond with it.

please note, the "habitable zone" is a region where liquid water can exist in orbit of a star on a planet, thus allowing life similar to earth norms provided the right conditions are present.

this is a huge topic but I wanted to start with the basics for anyone interested.
