About 4 minutes and thirty seconds.

I have to look at a list of algorithims though. I can't memorize all of them after solving the first two layers.

Timed, around 40 seconds. I'm pretty sure I've broken that by a few seconds, though those solves weren't timed. I'm just using a very basic F2L + some things I've figured out, but I would very much like to learn the Friedrich method. I'm sure I could break 30 easy. My main is an old no-name chinese DIY that I got before all these newer designs, haha! I tried a Haiyan's Haiyan Cube the other day, and it blew my cube out of the water, and now I really want to get some newer cube designs to try. I have a DaYan Guhong on the way now, I'm excited to receive it!

I'm calling bs on that claim. Unless you are a mathematical genius, there's no way you solved one without looking up algorithms or having no prior knowledge of how one is solved.

That's a joke...right?

No. It's not exactly easy to solve one by chance when there are 43,252,003,274,489,856,000 (yes that's the actual number) permutations in which the cubes can be arranged...and only one permutation that is considered solved.

I didn't come up with the calculation  :)
Quote
The original (3󫢫) Rubik's Cube has eight corners and twelve edges. There are 8! (40,320) ways to arrange the corner cubes. Seven can be oriented independently, and the orientation of the eighth depends on the preceding seven, giving 37 (2,187) possibilities. There are 12!/2 (239,500,800) ways to arrange the edges, since an odd permutation of the corners implies an odd permutation of the edges as well. Eleven edges can be flipped independently, with the flip of the twelfth depending on the preceding ones, giving 211 (2,048) possibilities.

Therefore,

    {8! \times 3^7 \times 12!/2 \times 2^{11}} \approx 4.33 \times 10^{19}

There are exactly 43,252,003,274,489,856,000 permutations, which is approximately forty-three quintillion.

That's an astounding number, but the potential permutations have nothing to do with physically solving the puzzle. You may as well state, "there are an almost infinite number of yoyo string tricks, and to discover the Double or Nothing mount without prior knowledge of such is impossible". A reductio ad absurdum counterpoint, certainly, but the only thing it takes to solve a Rubik's cube is a brain and a LOT of patience (and, presumably, the cube).

It is also important to note that the cube is sold in its solved state. Working backwards slowly, you could theoretically teach yourself the necessary movements without any math or outside coaching.

Solving the cube on PAPER (from "scratch"), however, would be an impressive mathematical feat.
