I am not sure if what we acquire from space is more than what we loose because of the earth rotation E.G Hydrogen.

Not exactly the same. At some point "shortly" after its formation, the early Earth was struck by a Mars-sized object, which threw untold gigatons of material off into space. Some of that material coalesced to form the Moon. That was probably the single biggest change in Earth's mass since its formation, however. The Earth HAS been accumulating junk from outer space (including the occasional asteroid or comet impact) but the mass of these impactors pales in comparison to the mass of the Earth itself. So to answer your question, I'd say that the Earth's mass HAS changed since its formation, but only once was that change significant and sudden, rather than minor and gradual.

No It was not,.. coz earth is recieving 1000s of space particals every day, but as consedring the ppl,.. it must make no change as ppl are comming from the components of the earth it self. and going back to it. only the particals which are leaving and comiing to the earth makes diffrence,.. like space shutels and (the moon which was part of the pasific ocien,...) So the Answer is : No the earths mass is not the same as it was on the first day of its formation.

No. A great deal of dust has fallen on the earth since its formation. I believe it's something like 20 tons per day.

Nope! Earth still, to this day, gets bombarded by stuff from outer space (meteorites, for example). That stuff gets added to Earth's mass (it's called accretion) at a rate of up to 22 million pounds a year.
I hope this helps.

certainly not...
Earth has increased in mass cuz it has been hit by many celestial bodies since its birth...
Even meteorites bombarding the earth add up to this increasing mass...
Gas or spacecrafts are the only things to escape earth and they dont even come close to matching the mass increased by meteorite bombardment

No. 30,000 - 40,000 tons of dust and debris fall onto the earth from space every year. Even all of the spacecraft that have been launched don't come close to that total.

I doubt it, the earth has been hit by a few meteors since it was formed, and the only losses could have been escaped gases and satellites placed in orbit.
