I need help finding relaible resources or input to back up a position that I was assigned to take in a debate. the postion that i must defend is that there is life on other planets. It could be just simple one cell life for all I care, any suggestions?

The only evidence for life on other planets so far is the mars meteorite that shows signs of possible fossilized bacteria. The Drake equasion is typically used to calculate the amount of life in the universe, but we don't know enough about the universe yet to fill in some of the final variables.

1. depends how yoy define what is life. when you connect a copper wire on a battery, the elctron is excited running from one end to the other end. is that life?
2. if you are talking about biological life. any planet that has salt water, life of single cell will be survived and readily combine with other cell. human are evolve from a complicated combination of many cells.
3. the first comet that hit the earth carried virus to the earth, virus life exist long before dinosaur.

The followinng is a popular science article that addresses this exact topic--and argues your exact position! It's in a science fiction magazine, ANALOG. But they routinely run science fact articles--and have an excellant reputation for quality and accuracy (besides, the author is a scientist himself!). The article includes a bibliography of scienntific and scholarly sources as well.

possibly mars at one time for maybe fossils on mars, but now the planet is 90% carbon dioxide which makes it unlivable.
there may be life on planets we do not know about yet.

For a fairly complete discussion of this which is pretty accessible to us amateurs can be found here:

The Drake Equation would be a good tool for that.
