That is one question that defies a definitive answer. Some theorists believe it has always existed (and that sidesteps the question) and others theorize that it may have been created by a race of super inter-dimensional beings and deposited here by way of a wormhole (who knows?!) But all in all, mathematics bears out the fact that it did, indeed, exist owing to the fact that universal expansion, if regressed, would wind down to a singular point (the ''singularity''). Beyond that, nothing is verifiable. But, till mankind has developed higher intellegence and accumulated enough knowledge to answer this question directly, perhaps it would serve to read the book of Genesis and interpret each of the Creator's 'Day' in terms of Billions of years.
well, hydrogen was the first basic atom in the beginning. gravity pulled the hydrogen atoms to form clouds and then condensed into balls of hydrogen gas. as the hydrogen gas condensed the atoms started moving quicker and quicker till fusion began. these were stars. then the hydrogen fused and became helium. as the stars aged they became unstable and the process slowed down and the hydrogen and helium started to fuse to become other atoms, such as neon or nitrogen. eventually these stars became so unstable that they exploded through supernovas in tremendous amounts of energy that allowed the formations of the heavier atoms. these heavier atoms spread out into clouds and the clouds condensed and the process started over and over again till we have all the atoms that we have to form planets and such.
The atoms within planets come from two different places. All the atoms heavier than helium would have been forged deep inside a heavy star. The atoms heavier than iron would have required a supernova, or colliding neutron stars, to form.
The hydrogen would have come either from a star or have been swept up from the interstellar medium. The same would be true for some of the helium. Another fraction of helium would result from the alpha particle decay of much heavier isotopes.
atoms came from positive and negative charges
All of the atoms except for hydrogen and some of the helium were made in the cores of stars. All of the hydrogen and many of the helium atoms were formed during the Big Bang.
The first atom condensed out of the energy released by the big bang.
HASSAN SAJJAD A GREAT MUSLIM SCIENTIST was able to see atom for first time ever although he didnt knew about it he named it as *rasheed*
in 1519
The first known antihydrogen atom was synthesized in 1995 at the CERN laboratory in Geneva. However, antimatter itself is produced constantly in the natural environment.
An ATOM!!!! An atom can be sub-divided in to protons, neutrons, and electrons.

First Germany second United States of America
Dalton didn't discover the atom. Democritus did. Dalton, however was the first to use the word atom. which comes from the GGreek word atomos, meaning "cannot be split"
The first model of the atom was developed by Thomson.
Rutherford presented the nuclear model of atom first.
split the atom
split the atom
This month
who was the u.s afraid would get an a atom bomb first
The atom was first split in a laboratory at University of Chicago in 1938.
No one has ever seen an atom
Greek philosophers Democritus and Leucippus were the first to seen that atom was made up if tiny pieces. John Dalton was the first person to tell people about atom.
