The Big Bang theory suggests that the universe began as an extremely hot and dense state around 13.8 billion years ago. Over time, matter and energy expanded and cooled, eventually giving rise to the formation of galaxies, stars, and eventually planets where life could potentially emerge.

Compared to the length of time for the first half-life of a sample of a radioactive isotope the length of time for the second half-life is?
The length of time for the second half-life is the same as the first half-life. Each half-life represents the time it takes for half of the radioactive atoms in a sample to decay. This process continues exponentially with each subsequent half-life.

Did supernovas exist before life on earth?
The first supernova was probably about 450 million years after the big bang, when the first, massive stars (Population III stars) exploded filling the Universe with the first heavy elements. These elements were "absorbed" by population II stars, which again exploded as supernovae. These metal enriched stars populated the Universe with the rest of the known elements. So supernova were around well before life on Earth. In fact without supernovae there would be NO life on Earth.
