Yes. Everybody is valuable. Until they die. Then only the things they’ve built and the ideas they’ve shared with others (including god) are all that is left to value. 

Technology (the evolution of human consciousness) is what we have made, and is the most valuable thing we can pass onto future generations, no matter whose babies they are. 

I may be full of bullshit, but I will always respect you and everybody else I meet in this short life. That is my small but valuable gift. 

 No, we can leave a genetic legacy. Someone to use the things we have built.
