By 'artifact', to clarify, I mean any non-active object that is recovered by humans. This would be anything that fits into a 'time capsule'
scenario, wherein they contacted us either by leaving something behind, somewhere, or we extrapolated their existence from something we found.
So, if an active, functioning probe were to come to Earth and transmit a greeting, that would be considered a 'direct' contact, in my poll, but if
one of our spacecraft came across a derelict alien probe or spaceship, that would be an 'artifact'.
