Do you believe in aliens and extraterrestrial life?  I do!
Yes, like Drake's equation, I have always speculated about the existence of intelligent life elsewhere!
What does Drake's equation state?
The equation summarizes the main concepts which scientists contemplate when considering extra terrestrial life.
So does it prove that there is extraterrestrial life?
No, but it offers a probabilistic argument that is used to estimate the possibilities.
that's cool - I say if it's possible, it's probable and there is ET life! Don't you?
Yes! There have been ongoing searches for signs since the mid-20th century!
Where abouts?  I know the midwest and America's heartland have been hot spots for evidence!
extraterrestrial life, and a narrower search for extraterrestrial intelligent life. Depending on the category of search, methods range from the analysis of telescope and specimen data to radios used to detect and send communication signals.
The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction. Over the years, science fiction has introduced a number of theoretical ideas, each having a wide range of possibilities. Many have piqued public interest in the possibilities of extraterrestrial life. One
way to stimulate scientific dialogue at a meeting on the search for extraterrestrial intelligence (SETI). The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. The equation is best understood not as an equation in the strictly mathematical sense, but to summarize all the various concepts which scientists must contemplate when considering the question of life elsewhere. The Drake equation is:

Drake's proposed estimates are as follows, but numbers on the right
