....

Some people even go to the moon. Does that mean our ancestors lived there?

Do you find cut-marks on antelope bones on the moon from 2.6 Ma like
you find on the savanna ?

All next to rivers. Most likely drowned or trampled when crossing rivers
during the trek. (I'm not claiming no hominid lived near rivers in savannas
etc.)
Some butcheries (SE.Asia IIRC) show traces of shells used to butcher them.
Also savanna?

Nobody claims some people kill antelopes.

(Did I say that? I forgot "not"?)

But the fact remains, early Homo was utilizing antelope bones on the
savanna 2.6 Ma, long before we got to the moon. So yes, our ancestors
lived on the savanna.
The point is that humans are superior to most typical savanna
dwellers:

Humans are superior to most typical polar dwellers, to most typical
forest-dwellers, most typical mountain-climbers etc.etc.

"The earliest Eurasians preferentially occupied
grasslands and open scrub- and wood-lands, as in
East Africa. Homo ergaster/erectus in East Africa after 1.7 Ma is
associated with hot and dry conditions, and open
grasslands;

Nobody denies the Pleistocene was generally more open & cold & dry, but that
does not mean that H.er lived on the open plains rather than at the
waterside!
RW Dennell cs.1988 "Early tool-making in Asia: two-million-year-old
artefacts in Pakistan" Antiquity 62:98­106 ... Most early hominid fossils
in Eurasia are highly fragmentary, usu.occur in water-lain sediments ... The
spatial associations betw.artifacts & animal bones in the earliest sites
(most occur in open fluvial, lacustrine or marsh deposits) are difficult to
interpret ... A few of the medium-sized & smaller ungulate-bones display
traces of marrow-processing, probably but not certainly made by hominids;
other items were gnawed by large or small carnivores , some were rolled by
water & abraded by waterborne sediments. ... The argument that early
hominids regularly hunted giant mammals is not well supported by the
available evidence ...
RW Dennell 2003 "Dispersal & colonisation, long & short chronologies: how
continuous is the Early Pleistocene record for hominids outside East
Africa?" JHE 45:421-440 ... appears to have preferred mosaic environments
that also contained permanent water & some wood- or scrubland, as well as
grasslands. ... The earliest evidence for hominids N of the Sahara is Ain
Hanech 36°N. The locality was situated in a flood-plain; grassland is
indicated by remains of Equus & gazelle, and open water by Hippo. ... In
theKashafrud Basin 36°N in NE.Iran, Oldowan-type stone artefacts were found
in the palaeo-shore deposits of a vast shallow Late Plio/Early Pleist.lake
.... Dmanisi ? probably only 60 km from the Caspian, which may then have
joined the Black Sea ... Pollen analysis indicates increasing aridity after
the hominid occupation ...

its post-cranial anatomy, with its long
limbs was geared to long-distance walking across
open ground, and to heat dispersal through upright
posture (Dennell 2003:442)."

Where does he get that?? This is nonsense: what mammals walk upright to
dissipate heat across open ground?? :-D Besides, the birds with rel.the
longest limbs are wading birds.
