According to some evolutionists, Mars had an atmosphere that was thicker than Earth’s  atmosphere. In their view, some 4 million years after the origin of the solar system Mars was already almost complete.

Mars’s atmosphere may have once been hundreds of times thicker than it is today, acting as a blanket that protected it from frequent asteroids that ravaged other planets

At this time, the planets existed in a vast ball of hot gas and dust that swirled around the young sun, called the solar nebula, which some planets would have temporarily absorbed into their atmospheres. However, once the solar nebula receded, it was thought that the planets would quickly have lost this gas, reducing the densities of their atmospheres.
