Are there other forms of life out there, or is Earth the sole cradle of life in this vast cosmic ocean? Where did life come from? How did life form? Just…what is life…and…why don’t we see any form of extraplanetary life?
To tackle this question, Dr. Frank Drake introduced what we now call the Drake Equation. It’s a tool—a way to estimate how many civilizations in our galaxy might be capable of communicating with us. While it’s not an exact science, it’s a fascinating way to break down the mystery into manageable parts.
