Read: John 4:1-15
The United States of America has spent millions of dollars to look for water on Mars. A decade ago, NASA sent two robots, Opportunity and Spirit, to Mars to see if water was present or had been present at one time. Why did the USA do this? Scientists who are examining the data sent back from those two space vehicles are trying to figure out if life ever existed on Mars. And for that to have happened, there had to be water. No water means no life.
