That's why you need a rocket engine to slow the craft.

My belief is less gravity would require energy to force bodies in a downard motion.

No offence, but your belief is simply wrong. Less gravity means things fall slower, but
any gravity will cause an object to fall to the surface.

Its kinda hard to prove or disprove as we have not been there to test this theory.

That is circular arguing. You say we haven't been there, then say we couldn't have been there because no-one has been there to test the practicalities needed to go there.

How amazing is it we can't or never landed a craft on the earth like the moon landing but 280,000 miles away with absolutely no proof of environment we can land on the moon but here where we can test land it we COULD NOT and NEVER was able to land a craft on earth like the ones used to the Moon.

Sorry, this also is simply wrong.
I accept you are in the 8th grade only. Fair enough. However, you must accept that you do not have all the facts or the experience needed to analyse them at your disposal. You are making blanket statements about things that do not exist or have never been done that are quite simply not true, and you are confusing 'I have never heard of' with 'they do not exist'. If you can't start by accepting that, then really there is no point in further discussion.
If you can accept that, I would ask you to look up the Lunar Landing Research Vehicle, which was exactly the kind of vehicle you said was never successfully landed. Look up the DC-X, which is another example. You might also consider the Hawker Harrier aircraft, which, although it uses a jet not a rocket, lands on more or less the same principle when performing a vertical landing.
You might also then look up the Soviet Luna probes, which included a number of soft landings, and even a few that landed and returned to Earth, and the NASA Surveyor series that made several soft landings on the lunar surface. These were unmanned probes. If unmanned probes can be soft-landed on the moon by remote control from Earth, or by automated methods, it would be a darn sight easier to land something with two men piloting it.
