Earth Is the Transmitter: Five Astrophysical Proofs of Directionality

Sun: 10 billion year main sequence
Sirius A: 1.64 billion year main sequence
Complex life requires 3.5+ Gyr (empirical).
Earth has the time. Sirius does NOT.

Solar system: 4.6 billion years old
Sirius system: ~250million years old
Ratio: 18.4×. Earth is 18× older.
Earth had complex life for 600 Myr.
Sirius system has existed for only 250 Myr.

Sirius B's progenitor star (~5 M☉) lived only
~100 Myr then became a red giant, sterilizing
the inner system. Any early planets destroyed.
Current planet (Sirius Bb) is frozen gas giant.

Sirius A HZ: ~3-4 AU (too much UV radiation)
Sirius B HZ: ~0.01 AU (Bb is at 0.9 AU = frozen)
Neither star currently supports a habitable planet
at the orbit where we KNOW a planet exists.

Earth: first life ~3.8 Gya → prokaryotes for
2 billion years → eukaryotes → multicellular
→ Cambrian explosion (540 Mya) → intelligence.
This required: stable star, stable orbit,
liquid water, magnetic field, plate tectonics,
ozone layer, Moon for tidal cycles.
The Sirius system provides NONE of these
at sufficient duration.

We did not come FROM Sirius.
We evolved HERE, on Earth, over 4 billion years.
If the pyramids transmitted toward Sirius,
WE were the senders.
Sirius was the TARGET, not the source.
