In a time far far away our Sun will have a super mega flare that wipes the hot sulfurous atmosphere of Venus clean away sparing Earth on the other side of the sun. Soon after, a massive comet swings behind the sun and appears to back into Venus tail first. After a thousand years the debris settles leaving evidence of a primitive salty ocean. Seeding Venus with as many heat tolerant lifeforms from Earth would begin with diatoms and advance in an evolutionary schedule on steroids. In a quarter million years Venus could be a Devonian paradise.
