I do not see (despite searching) and you do not provide any evidence of

That is self-referencing spam. Go dive into some tropic swamp then tell

There is point to wade only when carrying something. Otherwise swimming
is lot more energy efficient. But same is about bipedal movement in any
environment. Our ancestors possibly did wade as occasionally as humans
do now.

Zero links to proof of popularity of savanna hypothesis. That is your
false dichotomy straw man argument. But limitless number of kooks can
be wrong about same thing, each in its own way and so there are no
such dichotomy.

Still no idea what is your PA, and still no evidence besides some
kind of hostile stance towards that PA. Whatever PA can not add
any evidence that you do not have to you. Something happened,
rest of limitless possibilities did not. What happened happened
anyway in past and past is outside of sphere of influence of kooks.

Attempt to dodge with joke ... agriculture is likely only about 30K years
old so references to it are irrelevant. Benefit of forest for hunter and
gatherer however was left undiscussed.

Genetic evidence shows that we are farther from orangutans and
gibbons than from African apes. There are no fossils or tool findings of
your early Pliocene aquatic ape in Asia. There are enough fossils
and tool findings of non-aquatic ape in Africa from that time. By late
Pliocene however our tool using ancestors were all over the place.
So everybody conclude that these came out of Africa and spread
during late Pliocene. You never discuss that. What have few seashells
from early Pleistocene Java to do with any of it? Untold explanation
of yours. I repeat, even crow can find seashells there.

Lot of animals can swim noticeable distances when needed and that does
not make them aquatic enough to be worth mentioning. We find lot of
h.erectus tools in non-coastal locations. Who carried those there and
why? So tell us story of your version of Pliocene that fits with evidence.
Do not run away with insults.

I do not know who is sponsoring that savanna hypothesis. You never identify
them. You only use it as false dichotomy with your swamp ape.
