I'm a freshman in college - need a little help answering this "challenge question" in my biology book.
Exobiology is the study of life on other planets. In recent years, scientists have sent various spacecraft out into the galaxy in search for extraterrestrial life. Assuming that all life shares common properties, what should exobiologists be looking for as they explore other worlds?
Appreciate the help - thanks!

The first thing we are looking for is the presence of water or if water used to be there. We are also looking for evidence of metabolism in mineral deposits, as well as fossilized remains of microorganisms or other forms of life.

Oxygen rich atmosphere and some carbon dioxide, water, correct life-supporting spectral light, viable temperatures.

My first thought would be amino acids.
Life existed on Earth before there was oxygen so that doesn't need to be necessary.
