What would happen if the Moon Collided with the Earth?

THE MOON IS  THE ONLY NATURAL SATELLITE OF THE PLANET EARTH AND BY FAR, ITS THE ONLY SUCH OBJECT THAT HAS BEEN FORMED IN THE SOLAR SYSTEM TO HAVE CONDITIONS OF ICE, TO FORM LIFE, AND BY FAR THE ONLY ROCKS IN THE INNAR SOLAR SYSEM TO HAVE CONDITIONS TO SUSTAIN A LARGE OCEAN, COVERING THE ENTIRE SURFACE OF THE MOON, WHICH MEANS THAT HUMANS WOULD HAVE TO COVER UP AND FIND SOME WAY TO REMOVE THE DUST, BY CREATING VAPORTIVE ATMOSPHERE THAT REMOVES THE DUST.
BUT SCIENTISTS HAVE  QUESTIONED AND THEORIZED WHAT WOULD HAPPEN IF THE MOON COLLIDED WITH THE EARTH, RIGHT NOW IN THIS SECOND AS WE ARE SPEAKING, SO RIGHT NOW, SCIENTISTS ARE NOT SURE EXACTLY, BUT BASICALLY.

• WOULD INCREASE THE MASS
• WOULD INCREASE THE GRAVITY
• MAKING ALL DAYS PER TIME SEASON TO BE TO BE LONGER EQUALLY
• NO MORE COLD CONDITIONS
• ICE WOULD MELT DOWN AT THE  POLES
• WOULD,CREATE SOME NEW MOONS.
