The statements which are scientific are:

B.) The universe's average temperature and rate of expansion support the idea that it began as one super-dense and hot mass 13.8 billion years ago.

D.) Ocean tides are caused by the uneven gravitational pulls of the Moon and Sun on different parts of Earth.

A scientific statement is a statement based on various researches, experiments, measurable and empirical evidences in the experiment.

The opinions of random people do not in scientific theory.

Similarly, the comparison of human and other life forms based on intelligence is not supported by science. The whole biodiversity is required for proper maintenance of the earth.
