I think Lady Macbeth cares about what other people think. We can see that through her behavior towards her husband. She thinks he is unfit to rule because he is weak, and she is constantly trying to make him seem better in other people's eyes. She believes that she would be a much better ruler than him, if she were only a man. She is also trying to distract people from finding out who the real murderer is by fainting and drawing everyone's attention to her so that Macbeth wouldn't confess to his crimes.
Answer:
This is because scientists can only really guess how the earth started and got to this point. Even with evidence like fossils, etc. they still don't have clear answers for what really happened, and they still have no clue how the Earth was created in the first place, so that's why evolution is a theory. They know how gravity works so it is called a law. hope this helped! good luck! (:
