But such arguments should be backed with scientific facts.

But it is possible, if every scientific fact points towards it being both alive and human, which they do, then to say they don't have the same rights as every other person is oppression at best. While pretty much every right is relative to moral standpoints, the right to life of an innocent bystander isn't, because EVERYONE has the right to live unless they do something to lose that right; like murder, rape, or severe acts of violence.

While things like "The right to the pursuit of happiness." Or "The right to own property" COULD be argued as nothing more than "Abstract philosophical concepts", the right to life can't. Why? Well let me answer your question with one of my own;

Do you want to be killed? I won't even say "murdered" but just killed in general? Your answer is probably "No.", well if the right to life is just abstract, it doesn't matter WHAT you want. It wouldn't matter what I want. If no one had ANY rights, then we would be nothing more than animals, because rights are - at their core - basic entitlements granted to us by whatever force created us, that can not be legitimately revoked unless the person losing them does something to warrant them being taken away.
The exact definition of a right is this by the way;
A moral or legal entitlement to have or obtain something or to act in a certain way.
And the original (or as far back as I could find) definition was this;
An inalieable moral and/or natural right to have, obtain, or act a certain thing or way. (I know it doesn't change much but I just wanted to clarify)
