Non duality and eternal life

Is there really any evidence that anything goes beyond death ? By that I mean our self awareness. That our awareness transcends death? I know there is absolutely no concrete evidence of reincarnation. I'm not denying its possible. Just denying there is any scientific evidence However i have read claims that the self aware part of us-the part thats aware we are thinking goes beyond death and was here before birth ? Is there any hard evidence for this ?
