AFAIK, wrong.
The Power Cosmic makes SS nigh indestructable, massively strong, removes the need for oxygen, food, and sleep, gives him a cosmic direction sense, enables him to move at speeds approaching those of light(he must shift into hyperspace to exceed the speed of light), gives him telekinetic control of his board and allows him to project various forms of energy.
AFAIK, SS can only manipulate matter in standard human fashion-pick it up with his hands, etc. He cannot reconfigure atomic or molecular structure as Molecule man could. He can move his board telekinetically, but no other matter.
RE-Reality
The ability to manipulate all matter and energy might be the power to manipulate reality depending on how you define “manipulate matter and energy” and your view on quantum mechanics.
The ability to lift a mountain by will alone is not the ability to alter reality. It’s simply high grade telekineses. The ability to make E=M-C by will alone, now that’s the ability to alter reality. Changing the speed of light in a vacuum, altering the fabric of space/time so that triangles have 4 sides or 4000, making time flow backwards or sideways, changing the universe so that the shortest distance between any 2 points is not a straight line but a rhombus, those things constitute altering reality. That Beyonder had that power. He altered the laws of thermodynamics so that no living thing died or could die(After a talk with Molecule Man, he changed things back).
Currently, such power is found in small doses in the cosmic cubes and in an infinite amount in the reality gem. The reality gem is very difficult to use without the other 5. Without the omniscience granted by the collection, there are generally unforeseen and massively dangerous consequences. Still, Thanos was able to use the gem to ressurect Captain Marvel(the original, not his son). He did not raise his corpse. He merely will Mar Vell alive again. Mar Vell appeared in a healthy new body. When their chat was done, Thanos willed Mar Vell dead again. The body vanished.
If the Surfer had that kind of power, he would have raised Shalla Bal from the dead on his own long ago. Instead, he needed the aid of Adam Warlock and the Infinity Watch. The Silver Surfer, and Firelord watched and wept as Nova died. Neither had the power to save, let alone raise her. Firelord still mourns the loss of Airwalker.
While they would have good reasons for not simply walking down the streets raising the dead, SS has shown the willingness to raise certain individuals(Shalla Bal was resurrected in the 4 issue Resurrection, SS had to go up against Death and Mephisto). Why are Nova and Airwalker still dead? Because despite the Power Cosmic, the Silver Surfer and Firelord can NOT raise the dead.
