Sentence Correction

I don't understand why we use the present perfect although the action is done "140,000 years ago"
Does someone can explain?
Thanks.

Marc, what you are looking at is an entire expression, thought to have lived.

Is this the alternative you propose? thought to had lived

I guess the expression, though to have lived, is an idiomatic one.

Meanwhile, even if you didn't like D, E has a clear issue.

whom is the subject of had lived. whom ... had lived does not make sense. It should be who ... had lived.

I agree Marty. Actually, I've noticed the "whom..." in the sentence but was confused. I also keep in mind that "thought to had lived" is an idiomatic expression.

I take it you mean "thought to have lived".

One more way you won't get smoked next time!!!

Meanwhile, I think you would have been better off saying "I had noticed the 'whom'" or possibly, "I noticed the whom'".
