If everything has gravity, then everything should be spherical?

Another 5 word question :P
Well ok only planets have gravity , and even if have some gravity it can only get the dust around us thata are no more then an 1 sm awat from our body , yes then we might have some gravity but its very weak .
Well then the planet posses great gravity so yours really dont matter , but anyway birds are born in eggs most of them have more of a round shape , well maybe that goes only for eggs , but then if humans have gravity while baby is in the mom she got gravity too and you got pushed here and there while moving and while walking thats why you are not spherical (do you really wana be :D ) :P Blqh this is getting messy and stupid :D
The only gravity that effect us is the earth gravity so whatever the rest , they are toooooooo low ;)

Only something with a really large mass (like a planet) has enough gravity to make it spherical. The gravity of our bodies is very, very small. Also, planets are rotating quickly in space which started the spherical shape when they were forming.

I think the planet shape have more to do with the planet creation ;)
When the planet creates i think the gravity take all to the center and everything goes around equialy around it , and while its forming it takes sphere form :)
If think a fast rotating will make the planet look like some kind of disk since rotating will take away the mass , but well it needs a lot of speed to rotate that fast :)

Planets are created in swirling masses of dust from exploded stars (stars that have gone nova.) Everything is already rotating before the planets form. Spinning tends to pull things into a disk, but gravity tends to pull things in, so when things with great mass are spinning, a sphere is the compromise between the forces pushing out and the forces pulling in. When there is less mass, you do indeed get a disk (Saturn's rings are flat.) If there is much more mass than a planet, you can end up with things like neutron stars, where gravity has pulled everything in so tightly that one teaspoon of a neutron star would weigh billions of tonnes. A planet is a sphere instead of a disk, or instead of a tightly compact (although still spherical) rock because of the interactions of gravity and rotation.

Not everything has the same strength of gravitational pull aka g-force. That is why many things can retain their shape. It also matters with the composition of a matter like salt is always cubic in shape because of it's atomic structure unless shaped differently of course.
If you want to know more go to school and study.

I'm not sure here, but how did we ave gravity? Planets are round because they have gravity. We are not floating because we're being pulled by gravity.
You don't see stuff sticking to us right? Dusts that are on or skins are there because we passed through these dirt and the just happened to and on our skin.
