Once you are dead, someone (or rather a lot of people) are born to take your place on this world, and though they will not be you experiencing another life, but rather another person will exist who is experiencing a mutual human experience, and therefore you live on through these mutual experience. And indeed, under such a premise you are another person who has lived, and you've had mutual experiences with them. And although it might seem radicle to say you have probably experienced things that people have experienced hundreds of years ago, and perhaps you could have experienced something that some of our hominid ancestors have experienced. Or perhaps even had mutual experiences with animals and thus will "have lived" or "will live" as an animal in another life.
