Pokemon in a Laboratory?

Okay. So most of you know that Mewtwo, Porygon, Porygon2, and Porygon Z were made in a laboratory, right?

Well, were they even Pokemon? I mean, they were not created naturally (with an egg or something like that) and Mew was just a copy of another Pokemon. I don't see why they are Pokemon, let alone Mewtwo being legendary.

The info of each from the official site:

Porygon: The world's first artificially created Pokemon. It can travel through electronic space. (My note: Then why is it a normal type? Shouldn't it be electric?).

Porygon2: With planetary development software installed, it became capable of working in space.

Porygon Z: Additional software was installed to make it a better Pokemon (My note: You can't install software into a Pikachu or another Pokemon.) It began acting oddly, however.

Mewtwo: A Pokemon created by recombining Mew's genes. It is said to have the most savage heart among Pokemon.


So what do you think? After reading that info, I don't think it is possible that they can be real Pokemon. But that's just my opinion. What do you think and why? I would like to hear why some people would think they are Pokemon. There have got to be some pretty good reasons.

Thank you!
