The fallacies of gravity

just curious if anyone can explain these errors that many people are aware of when it comes to the theory of gravity

number 1. the way gravity reads, scientists have you think that objects of larger mass would have more of a gravitational pull then objects of smaller mass. so tell me how this makes sense

when we look at the sun we see the earth orbiting the sun, and the moon obriting the earth. if gravity were true, shouldnt our moon be orbiting the sun??? oh better yet, how come a planet way out in the distance such as neptune will orbit the sun, yet its moons will not orbit the sun??? something is wrong here, even at thise immense distances the moons will orbit the planets and not the sun, yet the suns "gravity" is strong enough supposedly to keep the planets in orbit.

number 2. why is it, only planets have orbits?? you could put a space shuttle in outter space and a astronaut will not orbit it. you could put the smallest pebbble into outter space and it will not orbit the space shuttle. why is this???? if gravity were true then surely such small objects would orbit larger ones, especially in space

number 3. on earth we see things that defy "gravity" on a daily basis. birds and airplanes for example. are you going to tell me that the gravity of the sun is strong enough to keep PLUTo in orbit but not an airplane or a little bird??????

number 4. scientists dont know how gravity works. or what it really is, and even then we see anaomolies in space that defy gravity

so my point is that gravity(like other scientifist "tHeories" is very on shaky grounds. it doesnt have the evidnece to back it up, and when examined critically it falls under the pressure(no pun intended )

show me a pebble that orbits a mountain or a bird that orbits the earth and then gravity will make sense. or better yet just show me how gravity works(if it works at all) and then maybe it will be more than just a theory

how do you evolutionsts explain gravity???
