Eeeegahhh, medicine man of the clan of the cheetah... he saw it first... and identified it as an omen that the next days hunt was to be successful...

of course I am limiting us to homosapiens...

Uk-Uk of the australiopithicus trib located in the rift vally saw it 3 million years ago... and thought "Ugh!"....

but the fact is we are ALL descended from the absolute first creature to first see that comet... so the people that the comet is named after are the descendants of its original discoverer... They were the lucky descendants that saw it again, and for the first time in the history of Earth had an inkling of what it really was...

Jacob... You gotta draw the line somewhere...
