The Moon is thought to have come from the Earth. In 1975, the giant impact hypothesis was put forward. This suggests that the Earth was hit by a planet about the size of Mars around the time of the formation of the solar system approximately 4.5 billion years ago, and the impact caused part of the outer layer of the Earth to spin off and form what is now the Moon.

Answer:
No.
Explanation:
I don't think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved because all other scientists also contributed in the work and work harder for it so the credit must be given to all scientists. If the credit will not given to other scientists so it is an unfair act so my opinion is against the credit given to Watson and Crick.
