Make your own Drake Equation calculation. You should do some research to determine reasonable numbers for the first few terms in the equation. For the last terms, you are free to choose a number you feel is appropriate. Describe what value you choose for each of the terms and defend the value with one or two sentences. Make sure the values you use for each term have the correct units or are a probability (or fraction) when appropriate. Finally, describe the final result (number of civilizations). Are you surprised by the number you calculated? PLEASE DON'T USE AI TO ANSWER THIS.
